The APM-7098 is a broadband distributed, 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 20 GHz or of an H or L diode mixer from 100 MHz to 30 GHz.  This amplifier can be operated with a variety of bias conditions for both low power and high-power applications. 


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

Min and Max limits apply only to our connectorized units and are guaranteed at TA=+25°C.  Die are 100% DC tested and RF tested on a per lot basis
