This is a x2 frequency multiplier with SMA connector input at 13 GHz and WR42 waveguide output at 26 GHz, it is a high quality product suitable for radio link applications, frequency sythesizers, beacon transmitters, radar applications, security applications, motion sensors, etc…
It is inserted in a milled aluminum block divided into two parts on a teflon substrate with beam lead multiplier diode and amplifier mounted with wire bonding technology. It is composed of an input attenuator to improve the input matching, pass-band filter, diode multiplier, second band-pass filter and a 100mW @ 24 GHz amplifier with direct waveguide output.
It needs three separate power supply voltages: +5V, -5V and a control voltage from +1.2V to +8.2V to tune the output power or fixed +8.2V to reach the maximum power. The attenuation of the input frequency is guaranteed at about -30dB thanks to a filter before the final power amplifier.
