The A-1844 from Marki Microwave is a RF Amplifier that operates from 18 to 44 GHz. It delivers a saturated output power of 16 dBm with a small gain of 17 dB and has a noise figure of 6 dB. This amplifier requires 3.5 V/-5 V DC supply voltage. The amplifier includes high frequency amplifier chips with all necessary biasing circuitry in a compact size to integrate directly into a system with only a negative control voltage (-5V, must always be applied first) and a positive bias voltage (3.5 V). Gain may be adjusted using the positive bias voltage or current. It can be used as an LO driver amplifier or a general purpose gain stage. The A-1844 is available in a module with 2.92 mm Male-Female connectors.
