Device Overview

General Description

The AMM-6702SM is a surface-mount LO driver amplifier that is designed to provide sufficient LO drive for an H or S diode mixer such as the MM1-1850HSM or MM1-1850SSM across temperature with input power from 0-10 dBm. This ferritic package offers improved resilience to radiative feedback and oscillatory behavior over the bare-die package option, providing the customer with a compact, high gain, wideband LO driver amplifier.

Electrical Specifications

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. Minimum test specifications are verified up to 44 GHz within an EVAL fixture due to the high insertion loss of the fixture above 45 GHz.
