RF amplifier with low phase noise

30 May 2022 Telecoms, Datacoms, Wireless, IoT

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.

The device uses GaAs HBT technology to provide low phase-noise performance and is optimised to provide enough power to drive the LO port of an S-diode mixer from 1 GHz to 18 GHz, or an H or L diode mixer from 1 GHz to 22 GHz.

The APM-7516 is available in a connectorised module that measures 2,85 x 1,5 x 1 cm, with 2,92 mm connectors. It can be operated under 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 amplifiers for S-, H- and L-diode mixers.
