SI4136-F-GM 개요
An RF frequency synthesizer is a clock-and-timing semiconductor that generates a controlled output frequency from a reference signal. It combines a voltage-controlled oscillator, phase detector, loop filter, and programmable divider in one package. The SI4136-F-GM integrates three VCOs so multiple RF or IF frequencies can be synthesized for wireless communications, WLAN, satellite radio, and related RF signal chains.
The verified distributor listings identify the SI4136-F-GM as a 2.5 GHz frequency synthesizer in a 28-pin VQFN exposed-pad package. Search results describe the device as an ISM RF synthesizer with integrated VCOs for wireless communications, while other listings identify RF wireless applications including WLAN and satellite radio. The operating supply range is listed as 2.7 V to 3.6 V.
The Si4136 architecture provides programmable divider and power-down settings through a three-wire serial interface. This allows a host controller to configure synthesis operating conditions during system startup or when changing RF channels. Integrated VCO resources can reduce the need for external frequency-generation blocks in RF receiver, transmitter, and down-conversion designs.
Typical applications include wireless LAN radio links, ISM-band communications, satellite-radio signal paths, RF receivers, and wireless transceivers. In these systems, the synthesizer supplies a controlled local oscillator or intermediate-frequency reference used by mixers, demodulators, and modulation blocks. The QFN package is intended for surface-mount assembly, while the exposed pad requires the PCB thermal and electrical land pattern specified by the manufacturer.
Designers should confirm the complete pinout, recommended decoupling, loop-filter implementation, reference requirements, and exposed-pad layout against the manufacturer datasheet. They should also verify operating conditions and replacement parts rather than relying only on distributor descriptions. The verified source data provides the package, frequency, supply range, interface type, and application class, but does not provide all pin names or detailed electrical limits.

일반적인 애플리케이션
SI4136-F-GM 적합 용도: 6 애플리케이션s: Wireless LAN RF Signal Generation, ISM-Band Wireless Transceiver, Satellite Radio RF Front End, RF Receiver Down-Conversion, Industrial Wireless Sensor Networking, RF Test and Measurement Equipment.
Wireless LAN RF Signal Generation
The SI4136-F-GM fits WLAN RF signal-generation blocks because the verified listings identify it as a 2.5 GHz RF synthesizer with three integrated VCOs and programmable divider settings. It can provide a controlled RF or IF reference for mixers, demodulators, and transmitters in 2.4 GHz-class wireless equipment. The 2.7 V to 3.6 V supply is suitable for a 3 V RF subsystem, while the three-wire serial interface allows a host controller to configure divider and power-down settings. Designers should verify channel coverage, lock time, phase noise, reference requirements, and loop-filter values against the manufacturer datasheet before finalizing the RF path.
추천
ISM-Band Wireless Transceiver
The SI4136-F-GM is applicable to ISM-band wireless transceivers because the supplied descriptions identify an RF wireless synthesizer with integrated VCOs and programmable divider functions. A receiver or transmitter can use the synthesizer to establish the local-oscillator or IF reference used by downstream mixers and signal-processing circuits. Its 2.5 GHz maximum listed frequency and 2.7 V to 3.6 V operating supply make it a candidate for compact wireless equipment, but the exact low-frequency limit, tuning granularity, output level, and channel-plan compatibility require manufacturer confirmation.
추천
Satellite Radio RF Front End
Satellite-radio front ends can use the SI4136-F-GM when the design requires programmable RF or IF synthesis in a compact wireless receiver. The verified distributor results explicitly mention satellite radio as an application, and the device combines three VCOs, phase-detection functions, loop filters, and programmable dividers in one RF synthesizer package. This integration can reduce external frequency-generation hardware, but the designer must account for the required reference frequency, loop bandwidth, phase-noise performance, output buffering, and exposed-pad thermal implementation.
추천
RF Receiver Down-Conversion
The SI4136-F-GM can support RF receiver down-conversion by generating the local-oscillator or IF reference required by mixer and demodulator stages. Its three integrated VCOs allow a receiver architecture to select among multiple synthesized outputs, while the three-wire serial interface provides a path for firmware-controlled divider and power-down settings. The 28-pin VQFN exposed-pad package supports compact RF layouts, although RF trace impedance, reference isolation, loop-filter placement, and output-buffer selection are application-specific and must follow the manufacturer’s recommended implementation.
추천
Industrial Wireless Sensor Networking
The SI4136-F-GM is suitable as a frequency-generation component in industrial wireless sensor and actuator systems that require stable RF references. Its three integrated VCOs and programmable divider settings can support configurable RF channels, while the 2.7 V to 3.6 V supply range fits low-voltage embedded systems. In an industrial design, the synthesizer must be paired with an appropriate reference source, loop filter, decoupling network, and RF matching structure. Temperature range, phase noise, lock time, and output power are not supplied and should be verified before using the part in harsh environments.
추천
RF Test and Measurement Equipment
The SI4136-F-GM can be used in RF test equipment when a programmable local-oscillator source is needed to exercise wireless receiver or transmitter chains. Its integrated VCOs and serial divider controls make it suitable for automated frequency selection and channel-oriented test sequences. The verified data supports a maximum listed frequency of 2.5 GHz and a 2.7 V to 3.6 V supply range, but laboratory use requires careful reference isolation, output-level calibration, loop stability checks, and thermal assessment. Detailed phase-noise and settling-time limits must be obtained from the manufacturer documentation.

설계 노트
The verified operating range is 2.7 V to 3.6 V. Place the recommended local decoupling capacitors close to the supply pins and follow the manufacturer’s capacitor values and placement because the supplied data does not specify the required capacitance or ESR. Keep the RF synthesizer supply return path short and use a quiet reference source to avoid injecting modulation or spur noise into the synthesized output.
The SI4136-F-GM uses a 28-pin VQFN exposed-pad package. Preserve the manufacturer’s land pattern, pad clearance, and exposed-pad connection rather than substituting a generic QFN footprint. Keep the reference, divider, and VCO-related traces compact and controlled, and route high-frequency outputs away from sensitive control signals to reduce coupling and phase-noise degradation.
Do not treat a related SI4136 suffix as a confirmed drop-in replacement without checking the complete ordering table. The supplied cross-reference results mention SI4136-F-GT, SI4136-F-BT, and SI4136-F-BM, but they do not verify identical pin functions, frequency limits, electrical ratings, or register behavior. Confirm package pinout, interface timing, supply limits, reference requirements, and RF performance before substitution.
The exposed pad provides the package heat-spreading path, but the supplied data does not provide thermal resistance or maximum power dissipation. Use the manufacturer’s exposed-pad and PCB thermal recommendations, provide adequate ground-plane copper, and avoid placing the package near heat sources that could destabilize the oscillator or RF output. Perform a thermal estimate with actual supply voltage, output configuration, and PCB copper before production release.
규정 준수 정보
The supplied search results identify the component and package but do not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Compliance status must be confirmed with the manufacturer or authorized distributor documentation.
