The APM-7098SM is a broadband low phase noise LO driver amplifier designed to provide a saturated +23 dBm output power with low DC power consumption. This amplifier uses GaAs HBT technology for low phase noise, and is optimized to provide enough power to drive the LO port of an S-diode mixer from 100 MHz to 18 GHz or of an H or L-diode mixer from 100 MHz to 22 GHz. This amplifier can be operated with a variety of bias conditions for both low and high-power applications. The APM-7098SM is packaged in a compact 4 mm QFN for surface mount integration on circuit board-based systems.


The electrical specifications apply at TA=+25 °C in a 50 Ω system.

QFNs are 100% RF tested.
