DESCRIPTION

This document describes the specifications for the

F1180 Dual Path RF Receiver consisting of an RF

Amplifier w/bypass function, Digital Step Attenuator

(DSA), and RF Mixer in each signal path. Applications

include Multi-mode, Multi-carrier BaseStation

Receivers & Repeaters. The F1180 supports the

following frequencies: RF from 1400MHz to 2700MHz,

LO from 1350MHz to 2900MHz, and IF from 25MHz to

400MHz. Refer to the Part # Matrix below describing

the complete series.

The F1180 RF front-end offers 16.5dB gain with 3.5dB

NF and +38dBm OIP3 performance at 2100MHz. The

digital step attenuator provides 30dB adjustment range

in 2dB steps via the SPI interface controller. For strong

signal conditions, each RF amplifier can be configured

to be internally bypassed via the SPI interface. The RF

front-end output and mixer input signals are bonded to

separate pins to allow interstage image-reject filtering.

Each of the dual mixer paths provide 8.2dB power

gain, 10.5dB NF and +35dBm OIP3 performance. An

external LO signal is applied to the mixer LO port.

This device is packaged in a 7 x 7 mm, 48-pin Thin

QFN with 50 ohm single-ended RF & LO inputs and

200 ohm differential IF output impedance for ease of

integration into the receiver lineup.
