QPB0066
®
Digital Controlled Variable Gain Amplifier (5ꢀ–ꢀ500ꢀMHz)
Product Overview
The QPB0066 is a digital controlled variable gain
amplifier featuring high linearity over the entire gain
control range with noise figure less of 4.3ꢀdB in its
maximum gain state. The gain of the dual 6-bit digital
step attenuators programmed with a 12-bit Serial
Peripheral Interface (SPI). The QPB0066 is packaged
in a small 6.0ꢀmmꢀxꢀ6.0ꢀmm leadless laminate MCM,
which contains plated through thermal vias for ultra-
low thermal resistance. The module is easy to use
with a few external DC blocks and RF chokes.
