Introduction

The IDTF1200 is a Digitally Controlled Intermediate Frequency Differential Variable Gain Amplifier for BaseStation and other commercial applications with a low IF frequency. The device offers extremely low Noise Figure over the entire gain control range. The device is packaged in compact 5x5 Thin QFNs with 200 ohm differential input and output impedances for ease of integration into the receiver lineup. Versions covering IF frequencies up to 300 MHz with low distortion are available.
