Introduction

This document describes the specifications for the F0562 2300MHz to 2700MHz dual-path sampled IF (SIF) receiver for use in multimode, multi-carrier base station receivers. Please refer to the part number matrix below, which describes the frequency coverage of the entire family. The family provides high-side or low-side LO injection options for all UTRA bands, and offers significantly better noise and distortion performance than currently available solutions. IF frequencies from 60MHz to 450MHz are supported. The F0562 SIF provides 29dB of gain with 47dB of gain adjustment in 1dB steps, and is designed to operate from a single 5V supply. Typically, the device delivers an output IP3 of +44dBm at an ICC of 480mA. Alternatively, the device can be configured in low current (LC) mode to reduce power consumption to <2W. The device is housed in a 10×10mm 68-pin thin QFN package, featuring 50Ω single-ended RF input and 200Ω differential IF output impedance for easy integration into receiver lineups. The 200Ω differential IF output can be readily matched to 100Ω differential per the application schematic.
