The AP-0010 from Marki Microwave is a positive bias, square wave driver amplifier that operates from 5 MHz to 10 GHz. The amplifier provides +24 dBm of saturated output power with small signal gain of 22 dB. This positive bias amplifier includes all necessary biasing circuitry for use directly in a microwave system - It requires a fixed 5 to 8 V positive bias. This amplifier minimizes the possibility of amplifier damage since no negative bias is required. The gain can be adjusted by varying the positive bias voltage or current. It can be used for generation of square wave LO drives for mixers (in saturation mode), general purpose LO drive signal generation or as a general purpose gain block for lab use (in linear mode). It is available in a module with connectors or a surface mount package.
