RF High-Power Relay

The Module includes a high-quality built & tested ENIG FR4 PCB (27.5 x 39 mm) that comes with 3 female SMA conenctors soldered in place.

50 Ohm contact
0.25 dB max attenuation at 3 GHZ
40 dB min isolation
More than 40W CW power handling
It is designed with a 50-Ohm contact and works very nicely up to 3 GHZ and more!
It can handle 40-50 W of RF power at 3 GHZ! It’s insertion loss is very low at 0.25 dB max while the isolation of the non-selected port is >40 dB.
The relay’s coil is specified for 5 VDC operation but the PCB module is designed for powering the relay with a MOSFET switch and is equipped with resistors for 13.8 VDC system voltage.
This can be changed by altering the values of the resistors R1 and R2. Extensive filtering is used and balanced snubbing to reduce voltage transients to any system this module will connect with.

The MOSFET gate will accept a 3.3V or 5V TTL High signal to activate the relay. A green LED will light and altogether will consume around 35 mA.

J4 PIN-OUT

PIN 1 LOGIC HIGH (3.3 V OR 5 V LEVEL) TO ACTIVATE THE RELAY

PIN 2 GROUND (0 VDC)

PIN 3 +13.8 VDC (or 12 VDC)
