SI4136-F-GT 概要
An RF frequency synthesizer generates a stable, programmable output from a reference frequency by comparing a divided output with a divided reference and correcting the VCO through a feedback loop. In the Si4136, three integrated VCOs, resonators, varactors, loop filters, phase detectors, and programmable dividers reduce the number of external RF components required. This integration is useful when a wireless product needs both IF and RF synthesis from one IC.
Verified feature data identifies low phase noise, minimal external-component requirements, a 5 µA standby current, and a 25.7 mA typical supply current. A three-wire serial interface programs divider and power-down settings. The 2.5 GHz capability makes the part applicable to ISM wireless transmitters, receivers, WLAN radio designs, and other RF communication equipment, provided the selected output frequency and channel plan fall within the device's specified operating limits.
The 24-TSSOP package is designed for surface-mount PCB assembly, but RF performance depends on controlled grounding, short supply connections, clean reference routing, and careful output matching. Power-supply decoupling and loop-filter layout should follow the manufacturer datasheet and reference-circuit recommendations. The integrated synthesizer simplifies BOM size, yet PCB parasitics, reference jitter, antenna coupling, and thermal conditions can still affect phase noise and lock behavior.
This page consolidates the verified distributor description, package information, feature snippets, pricing evidence, and cross-reference search results for SI4136-F-GT. It also distinguishes verified drop-in alternatives from unsupported replacements; no cross-brand drop-in equivalent was established by the supplied data.
Designers should verify the complete electrical limits, register map, pin names, and reference configuration in the applicable manufacturer datasheet before release. Especially, the product is a frequency synthesizer rather than a complete RF transceiver, and its performance must be evaluated together with the external reference, matching network, antenna path, and system power architecture.

主な用途
SI4136-F-GT の用途: 6 件s: WLAN RF and IF Synthesis, ISM Wireless Transmitter, Wireless Receiver IF Generation, RF Communication Test Equipment, RF Module and Gateway Platform, Industrial Wireless Sensor Network.
WLAN RF and IF Synthesis
The SI4136-F-GT fits WLAN radio signal-generation blocks that need programmable RF and IF synthesis from a single IC. Its three integrated VCOs, loop filters, dividers, and phase detectors reduce the number of external synthesizer functions, while the verified 2.5 GHz maximum stated frequency targets RF wireless designs. In implementation, connect a stable reference, configure the divider and power-down settings through the three-wire serial interface, and validate output level, lock range, and channel spacing on the final 24-TSSOP PCB. The device is a synthesizer block, not a complete transceiver, so PA, mixer, antenna, filtering, and receiver functions remain separate.
おすすめ
ISM Wireless Transmitter
The SI4136-F-GT is suitable for an ISM wireless transmitter when the required carrier and intermediate frequencies are within the verified 2.5 GHz maximum and the reference architecture matches the device. Its integrated VCOs and loop filters can simplify frequency-plan implementation, while the programmable serial interface allows divider and power-down configuration. RF layout still determines whether the synthesizer delivers acceptable phase noise and spur performance. Keep the reference and supply paths short, preserve impedance control, and measure lock behavior across temperature and supply tolerance before integrating the transmitter power stage.
おすすめ
Wireless Receiver IF Generation
The SI4136-F-GT can provide programmable IF synthesis for wireless receiver architectures because the verified manufacturer description explicitly identifies IF as well as RF synthesis. The three VCOs and programmable divider network allow a receiver front end to share local oscillator generation with transmit or conversion functions. The integration helps control board area, but the receiver still needs adequate filtering, isolation, gain distribution, and reference cleanliness. Engineers should evaluate image rejection, LO leakage, phase noise, and spur levels together rather than treating the synthesizer's nominal frequency as a complete receiver-performance specification.
おすすめ
RF Communication Test Equipment
SI4136-F-GT is useful in RF communication test equipment that needs a compact, programmable frequency source for exercising receiver or transmitter chains. The verified 2.5 GHz maximum stated frequency and three-VCO architecture support multi-output or multi-plan testing, while the low-power 5 µA standby current can help preserve instrument standby consumption. A practical implementation still requires an external reference, output matching, attenuation or amplification as appropriate, and calibration of frequency and level. Confirm lock time, output power, tuning granularity, and phase noise against the instrument specification using the completed board and fixture.
おすすめ
RF Module and Gateway Platform
The SI4136-F-GT can serve as the local frequency-synthesis element in an RF gateway, wireless bridge, or compact communications module. Its integrated VCOs and loop filters reduce the number of discrete synthesizer blocks needed when the platform requires both RF and IF outputs. The 24-TSSOP package supports automated surface-mount assembly, but RF module designers must still control antenna coupling, reference routing, ground continuity, and thermal rise. Validate output isolation so multiple VCO paths do not create unacceptable leakage or intermodulation, and verify regulatory channel requirements separately from the IC's nominal maximum frequency.
おすすめ
Industrial Wireless Sensor Network
SI4136-F-GT is a candidate for industrial wireless sensor networks when a node or gateway requires programmable RF synthesis near the RF front end. The verified low standby current of 5 µA and typical supply current of 25.7 mA make power state planning important, especially in battery-powered equipment. Since the IC synthesizes frequencies but does not replace the sensor interface, RF amplifier, or antenna, the platform designer must allocate separate blocks for sensing and transmit power. Confirm the reference's availability during sleep and wake transitions, prevent unintended VCO activity through the power-down setting, and test channel stability across the complete environmental range.

設計ノート
Keep the reference, serial-interface, supply, and RF paths short, and preserve a continuous ground reference beneath and around the 24-TSSOP. Place decoupling capacitors at the supply pins and route the three-wire interface away from sensitive VCO and output nodes where practical. RF synthesizer performance can be degraded by long traces, discontinuous return paths, and unintended antenna coupling even when the nominal divider and VCO functions are correct.
Design the supply network around the verified 25.7 mA typical supply current and the 5 µA standby-current value. Confirm the permitted supply-voltage range, startup behavior, and power-down sequencing in the manufacturer datasheet before selecting capacitors or regulators. Estimated: if the design operates at 3.0 V and consumes 25.7 mA, supply power is about 77.1 mW; this is an arithmetic estimate, not a datasheet power specification.
Validate reference jitter, phase noise, lock range, output level, and channel-to-channel isolation on the assembled PCB. A clean digital programming interface does not guarantee a clean RF output; loop-filter settings, VCO routing, reference spurs, impedance discontinuities, and nearby switching circuitry can dominate measured performance. Use controlled test points and calibrated RF equipment rather than inferring phase-noise performance from nominal frequency alone.
Do not treat SI4136-F-GT as a complete RF transceiver. The IC provides synthesis functions, while matching networks, filters, amplifiers, antenna paths, and receiver conversion stages may still be required. Also do not assume that the listed 2.5 GHz maximum is the complete tuning range without checking the manufacturer specifications, and do not use an unverified substitute without checking the complete pin map and register interface.
