PIN Diode 100W RF TR Switch

PIN Diode 100W RF TR Switch

Why Choose This?

Traditional RF relays are expensive, slow, noisy, and wear out after 10K–100K cycles. This solid-state TR switch RF module solves all of that — offering virtually unlimited operational life, no mechanical noise, low insertion loss, and switching speeds in the microsecond range.

Key Features

• Wide Frequency Coverage: Optimized performance from 230 MHz to over 3 GHz (base IC rated 50 MHz–6 GHz)
• MACOM MASW-000936-14000T PIN Diode IC: 3 integrated PIN diodes in a compact 4mm QFN package
• Efficient Driver Design: Single-chip IXYS IX4425 MOSFET driver handles phase-reversed control signaling — no complex external circuitry required
• Low Voltage Operation: Runs reliably on 12V (no need for the specified 28V), eliminating the need for a noise-inducing DC/DC converter — keeping your receive noise floor clean
• Low Current Draw: Under 0.5A required for full operation
• Enhanced Isolation: Shunt PIN diode architecture plus an additional receiver-input diode for superior TX/RX and ANT/RX isolation
• Premium PCB Construction: 4-layer Rogers R4003/FR4 hybrid stack-up with dedicated ground planes for stable impedance and built-in heat dissipation — the board itself acts as a heat spreader
• Professional-Grade Materials: ENIG-finished R4003 board (57 x 48 mm, 1.6mm thick), all SMD components factory pre-soldered
• Flexible Connector Options: Pre-cut mounting for N-type female connectors (TX/ANT ports, not included); RX port comes with SMA female pre-installed
• Enclosure-Ready: Designed to fit standard enclosures such as the HAMMOND 27134PSLA, with support for an optional copper heat-spreader plate for high-power thermal management

Important Usage Notes

Proper sequencing is essential for long service life. Always:

• Confirm your antenna presents a low VSWR before transmitting
• Cut RF power before switching states
• Switch the TR switch to TX before applying transmit power
• Allow brief settling time when transitioning from TX back to RX before re-enabling your receiver front end

Full switching sequences typically complete within 10–20 microseconds when properly implemented. Following the recommended sequencing procedure ensures maximum lifespan and protects both your transmitter and this module from overshoot or mismatch damage.
