800 - 1000 MHz High Linearity Silicon Germanium Polar Modulator

Stanford Microdevices 

Product Description

The Stanford Microdevices’ SCP-1016 polar modulator is a

unique component designed to simplify the correction elec-

tronics used on high linearity power amplifiers. This high

linearity device provides amplitude and phase adjustment

through two independently modulated control voltages.

The SCP-1016 is fabricated using silicon germanium

device technology and delivers 15dB of amplitude adjust-

ment and greater than 360 degrees of phase adjustment.

The broadband design of this component results in out-

standing amplitude and phase flatness as required in many

correction circuit architectures. This device also includes a

fast shutdown feature that can be used to protect subse-

quent amplifier stages from excessive RF overdrive.
