The APM-6848SM is an integrated 2-stage broadband, low phase noise LO driver amplifier designed to provide a saturated +20 dBm output power from a 0-6 dBm input power with low DC power consumption, packaged in a 4mm QFN.  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 2 GHz to 20 GHz or an H or L diode mixer from 2 GHz to 32 GHz.  This amplifier can be operated with a variety of bias conditions including VC=VB=5V for both low power and high power applications.


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