BGX7220HN: Dual receiver down mixer

Overview

The BGX7220 device combines a pair of high performance, high linearity down-mixers for use in receivers having a common local oscillator, for instance having main and diversity paths. The device covers the frequency range from 700 MHz to 950 MHz. Each mixer provides an input 1 dB compression point (ICP_1dB) above 13 dBm, with an input third-order intercept point (IP3_i) of 26 dBm. The small-signal Noise Figure (NF) is below 10 dB whereas under large signal blocking conditions the Noise Figure is typically 20 dB. Isolation between mixers is typically 55 dB.

Features

700 MHz to 950 MHz frequency operating range
Conversion gain 8 dB in the 900 MHz band
13 dBm input power at 1 dB gain compression point
26 dBm input third order intercept point
10 dB typical small signal noise figure
Integrated active biasing
5 V single supply operation
Independent power-down hardware control pins per mixer
Low bias current in Power-down mode
Matched 50 Ω single-ended RF and LO input impedance
ESD protection at all pins

Target Applications

Mobile network infrastructure
RF and IF applications
Communication systems and radars
Microwave and broadband
Industrial applications
