Microwave prescaler is made with smd components on two-sided pcb 33 x 65 mm. The prescaler's ratio can be selected between 1:10 or 1:20 or 1:40. The prescaler has a rf amplifier and it's input is protected with Schottky diodes.

Maximum input frequency is over 1200 MHz in range from -30dB to +10dB. Power is from +8V to +12V DC at max. 30mA.
