SI4113-D-GM 개요
A frequency synthesizer is a timing and RF signal-generation IC that combines frequency reference, phase detection, feedback-divider, voltage-controlled oscillator, and loop-filter functions into a controllable frequency-generation system. In the broader hierarchy, it belongs to clock and timing ICs, RF synthesizers, RF signal-generation devices, and wireless-communications semiconductors. Integrated VCOs reduce the need for discrete varactor diodes, external oscillators, and separate passive matching networks.
The SI4113-D-GM is reported to operate across 900 MHz to 1800 MHz in one band and 750 MHz to 1500 MHz in the other. Its output power spans -14 dBm to +1 dBm, while harmonic performance is listed from -26 dBc to -20 dBc. These values make it relevant to compact wireless transmitters and receivers operating in cellular, personal-radio, and other RF communication bands.
Its integrated synthesis architecture supports RF1 and RF2 outputs and is intended to isolate external interference in silicon. The 2.7 V to 3.6 V operating supply aligns with low-voltage portable RF systems. Reported current of 18 mA to 27 mA gives engineers a concrete starting point for power-budget analysis, although exact current depends on operating mode and output configuration.
Typical uses include dual-band transceivers, wireless personal-communications equipment, IF synthesizers, and RF up-conversion or down-conversion chains. The component can simplify boards by consolidating frequency-generation functions, but RF layout still requires controlled impedance, short return paths, suitable grounding, and separation between sensitive synthesis nodes and radiating paths.
Designers should verify the complete pinout, loop-filter guidance, reference requirements, and output-matching network in the manufacturer datasheet before layout. Supply decoupling should be placed close to the device, and the exposed pad needs the package-specific thermal and assembly treatment documented by Skyworks Solutions. The major engineering trade-off is board simplification versus careful RF routing and application-specific filter tuning.
This page consolidates the verified manufacturer and distributor facts, distinguishes confirmed specifications from missing datasheet data, and provides practical replacement and selection guidance beyond a raw catalog listing.

일반적인 애플리케이션
SI4113-D-GM 적합 용도: 6 애플리케이션s: Dual-Band Wireless Transceiver, Wireless Personal-Communications Equipment, RF Up-Conversion and Down-Conversion, IF Frequency Synthesis, Low-Power Wireless Communication Module, Portable RF Test and Measurement Front End.
Dual-Band Wireless Transceiver
The SI4113-D-GM fits a dual-band wireless transceiver requiring IF and RF frequency synthesis within 750 MHz to 1800 MHz, depending on the selected band. Its RF1 and RF2 outputs allow the synthesizer to support transmit and receive conversion paths while three integrated VCOs reduce external frequency-generation hardware. The verified 2.7 V to 3.6 V supply and 18 mA to 27 mA current provide a starting point for portable RF power budgets. Board implementation still requires controlled RF routing and manufacturer-recommended filtering.
추천
Wireless Personal-Communications Equipment
The SI4113-D-GM is explicitly positioned by Skyworks Solutions for wireless personal communications, where compact, low-power RF synthesis can reduce passive count and eliminate external VCOs or varactor diodes. Its 900 MHz to 1800 MHz and 750 MHz to 1500 MHz bands cover common RF operating regions used in portable communications equipment. The verified -14 dBm to +1 dBm output range is suitable as an architecture input, but the final output power must be coordinated with the power amplifier, antenna network, and applicable regulatory limits.
추천
RF Up-Conversion and Down-Conversion
Use the SI4113-D-GM when a wireless signal chain needs programmable RF generation for up-conversion or down-conversion. The two documented RF outputs, RF1 and RF2, provide separate synthesis paths for RF signal-chain stages, while the 1.8 GHz maximum frequency supports high-band wireless designs within the documented limits. Integrated VCOs can simplify the RF front end by removing discrete oscillator and varactor assemblies. Engineers must still validate mixer isolation, matching-network loss, spur levels, and output drive at each supported channel.
추천
IF Frequency Synthesis
The SI4113-D-GM is described as performing IF as well as dual-band RF frequency synthesis, making it applicable to receivers and transmitters that need an intermediate-frequency local oscillator. Its three integrated VCOs support multiple synthesis functions within one IC, reducing board area and external component count. The documented 2.7 V to 3.6 V supply is suitable for compact low-voltage RF systems, while the 18 mA to 27 mA current range helps estimate battery and thermal budgets. The reference path and loop-filter implementation should follow the manufacturer datasheet exactly.
추천
Low-Power Wireless Communication Module
The SI4113-D-GM is appropriate for compact wireless modules that need low-noise RF synthesis without the component count of a discrete VCO implementation. Skyworks Solutions specifically identifies reduced external passive count, elimination of external VCOs and varactor diodes, and improved power efficiency as design benefits. The verified 18 mA to 27 mA operating-current range is useful when sizing a portable power budget, but average consumption should be measured across the intended operating states. RF shielding, ground-plane continuity, and antenna isolation remain essential in a finished module.
추천
Portable RF Test and Measurement Front End
The SI4113-D-GM can serve as the RF synthesizer in a portable test front end that generates local-oscillator or conversion signals for wireless-component testing. Its documented bands of 750 MHz to 1500 MHz and 900 MHz to 1800 MHz cover many common RF test points, while RF1 and RF2 outputs can support alternate conversion architectures. The output range of -14 dBm to +1 dBm is a useful starting point, but instrumentation designers must add appropriate attenuation, calibration, and gain control. Reference noise and loop-filter settings determine achievable phase noise.

주요 차별점
- Integrated dual-band RF synthesis (vs SI4133-D-GM)
- Documented RF1 and RF2 output paths (vs SI4113-D-GMR)
- Low-voltage wireless integration (vs SI4113-BT)
설계 노트
Route RF1 and RF2 as controlled-impedance RF paths with short connections, continuous ground-plane return, and minimal stubs. Keep the reference input and feedback-related routing away from antenna and high-power RF paths to reduce crosstalk and unwanted coupling. Validate the final layout with the manufacturer's reference design when available, because the verified data identifies the 28-VFQFN exposed-pad package but does not provide a complete layout drawing.
Use the documented 2.7 V to 3.6 V supply range and the reported 18 mA to 27 mA current range for initial power-budget calculations. Place local supply decoupling at the device's power pins and maintain the recommended exposed-pad connection and thermal path. Do not treat the current range as a guaranteed average consumption; measure the configured operating mode because synthesizer activity and output state can change the actual demand.
Do not assume that a related SI4113, SI4133, or SI4113-D-GMR ordering code is automatically a drop-in replacement. Confirm package body dimensions, exposed-pad geometry, pin numbering, RF output assignments, programming registers, reference frequency, loop-filter requirements, and absolute maximum ratings against the manufacturer datasheet. The supplied web results establish related products but do not establish full pin compatibility.
