The APM-7516 from Marki Microwave is a low-phase noise amplifier that operates from 1 to 22 GHz. This amplifier provides a saturated output power of 23 dBm and a small signal gain of 12.5 dB with a noise figure of 5.1 dB. It can handle up to 20 dBm of input power and has a phase noise of -165 dBc/Hz at 10 kHz offset from the carrier frequency.
This amplifier uses GaAs HBT technology to provide low phase noise performance and is optimized to provide enough power to drive the LO port of an S-diode mixer from 1 GHz to 18 GHz or of an H or L diode mixer from 1 GHz to 22 GHz.
The APM-7516 is available in a connectorized module that measures 1.12 x 0.59 x 0.41 inches with 2.92 mm connectors. It can be operated with a variety of bias conditions for both low power and high-power applications such as mobile test and measurement equipment, radar and satellite communication, 5G transceivers, and driver amplifier for S, H, and L-diode mixers.
