SI4113-D-GT Übersicht
A frequency synthesizer generates or translates a stable, programmable reference into an RF carrier used by wireless transmitters, receivers, and related communication equipment. The SI4113-D-GT combines a phase-locked loop with integrated voltage-controlled oscillators and RF output circuitry. Its dual-band architecture supports wireless personal-communications designs where compactness, low power, and reduced external component count are important.
The verified distributor information identifies RF1/RF2 outputs, a 1.8 GHz operating frequency, one synthesizer circuit, and a 24-pin TSSOP package. Skyworks states that the device targets price-sensitive, low-power, high-performance personal wireless communications by reducing passive components, eliminating discrete VCOs and varactor diodes, improving power efficiency, and isolating external interference in silicon. These features make it useful in RF modulation and demodulation chains requiring local frequency generation.
The part also appears in distributor listings under both Skyworks Solutions and legacy Silicon Laboratories naming. This distinction matters when searching for documentation or inventory: the manufacturer history is reflected in the search results, while the current distributor records identify Skyworks Solutions. The exact RF output power, tuning range, phase-noise figures, supply voltage, and control-interface details were not included in the supplied records and require confirmation from the manufacturer datasheet.
Typical design uses include dual-band wireless transceivers, RF modulators, RF demodulators, IF-generation stages, compact communications modules, and low-power RF front ends. In a transmitter, the synthesizer can create the carrier or intermediate frequency while the PLL locks its output to a stable reference. Designers should preserve controlled impedance on RF traces, provide suitable grounding and decoupling, and verify loop-filter settings against the intended channel plan.
The main design tradeoff is integration versus specialized flexibility: integrated VCOs simplify the BOM and reduce external interference pickup, but RF performance, output power, and frequency limits must be confirmed against the exact system requirements. The verified source record does not provide a manufacturer datasheet URL, complete electrical limits, or a full pinout, so those details remain explicitly unconfirmed rather than inferred.
This page combines distributor specifications, package information, source links, application guidance, and a strict validation framework so engineers can distinguish verified facts from parameters that must be checked in the manufacturer datasheet.

Typische Anwendungen
SI4113-D-GT ist geeignet für 6 Anwendungs: Dual-Band Wireless Transceiver, RF Modulator Signal Chain, IF Generation Stage, Low-Power Wireless Module, RF Demodulator Front End, RF Test and Measurement Equipment.
Dual-Band Wireless Transceiver
The SI4113-D-GT fits a dual-band wireless transmitter or receiver when the system needs programmable RF or IF generation close to the RF front end. Its verified 1.8 GHz operating point and RF1/RF2 outputs provide the basis for local carrier or intermediate-frequency synthesis, while integrated VCOs reduce the external VCO and varactor-diode count described by Skyworks. The design must still verify frequency coverage, output power, phase noise, reference requirements, and channel-plan margins before selecting the device.
Empfohlen
RF Modulator Signal Chain
In an RF modulator signal chain, the SI4113-D-GT can generate a stable local carrier or intermediate frequency for mixing, modulation, or frequency conversion. The verified distributor description identifies the part as an RF synthesizer with RF1 and RF2 outputs, which supports routing one synthesis resource according to the modulator architecture. Integrated VCOs simplify the RF chain, but the exact output level, tuning sensitivity, phase-noise contribution, and loop-filter requirements must be confirmed from the manufacturer datasheet.
Empfohlen
IF Generation Stage
The SI4113-D-GT is suitable for an IF-generation stage in wireless equipment where a local oscillator must be derived from a stable reference rather than a discrete VCO network. The cross-reference records describe a related synthesizer entry with a 2 MHz to 26 MHz reference input and 1720 MHz output, but those values should not be assumed to define every SI4113-D-ZT1 or SI4113-D-GT variant. Confirm the exact frequency plan, reference multiplier, output impedance, and lock behavior in the current datasheet.
Empfohlen
Low-Power Wireless Module
The SI4113-D-GT can support compact wireless modules where reducing external components and isolating external interference are priorities. Skyworks specifically describes the device as addressing price-sensitive, low-power, high-performance personal wireless communications while reducing passive count and eliminating external VCOs and varactor diodes. A compact module still needs careful supply decoupling, reference routing, controlled-impedance RF traces, and thermal validation; the verified records do not state the exact supply voltage or current consumption.
Empfohlen
RF Demodulator Front End
For RF demodulator designs, the SI4113-D-GT may provide a local oscillator or IF reference for a receiver signal path. The two-output architecture can simplify channel-specific routing when the receiver requires separate synthesis paths or different conversion relationships. Engineering validation must cover image rejection, LO leakage, phase noise, spur behavior, lock range, and coexistence with sensitive analog stages; only package and headline frequency information are confirmed in the supplied distributor records.
Empfohlen
RF Test and Measurement Equipment
The SI4113-D-GT can be evaluated for RF test equipment that requires a compact programmable source for calibration or IF injection. Its integrated VCO architecture reduces the number of discrete frequency-generation components that must be assembled and maintained. For instrumentation-grade use, verify tuning resolution, frequency accuracy, phase noise, output purity, reference jitter, temperature drift, and calibration requirements. The available search data does not provide those exact numerical limits, so laboratory qualification is required before production use.

Wichtigste Unterscheidungsmerkmale
- Integrated RF frequency synthesis in a single IC (vs. Discrete VCO implementation)
- RF1 and RF2 output architecture (vs. SI4113-D-GTR)
- 1.8 GHz device positioning (vs. SI4113-BT)
- Compact 24-pin TSSOP implementation (vs. Discrete VCO plus external synthesizer components)
Designhinweise
Route RF1 and RF2 as controlled-impedance RF traces, using the shortest practical connection from the device to the matching network and keeping return-current paths continuous over a solid ground plane. Keep the reference input and feedback routing compact and isolated from RF outputs where practical. Use the manufacturer reference layout and land pattern for the exact 24-pin TSSOP ordering code before fabrication.
Place supply decoupling capacitors at the power pins and preserve a low-impedance ground return for the synthesizer. Because the supplied records do not state the recommended supply voltage, capacitor values, or current consumption, do not infer those values from generic RF designs. Select components only after reviewing the Skyworks datasheet and its recommended application circuit; validate supply ripple during PLL lock and RF output activity.
Evaluate the reference clock, loop-filter implementation, and RF output matching as a single signal-chain design. Harmonic spurs and phase noise are influenced by supply noise, reference jitter, layout coupling, and the selected loop bandwidth. Use shielded or separated reference routing where needed, and measure both locked and unlocked behavior across the intended frequency range rather than relying only on nominal synthesizer frequency.
Do not treat a same-package comparison listing as proof of drop-in compatibility. Verify pin names, power sequencing, reference input range, RF output assignment, control registers, frequency limits, and package drawing before replacing SI4113-D-GT with any related part. Also confirm whether the records are current Skyworks documentation or legacy Silicon Laboratories documentation, because manufacturer history can otherwise cause mismatched datasheets.
