GENERAL DESCRIPTION
Ideal for Multi-Carrier Systems
Lowside or Highside LO
11.7dB Gain
This document describes the specification2 for the
IDTF1763 Zero-DistortionTM Highband RF to IF Single
Downconverting Mixer. This device is part of a series of
mixers using lowside or highside LO injection options for
all UTRA frequency bands. See the Part# Matrix for the
detail of all devices in this series.
Ultra linear +45dBm IP3O using HS LO or
+42dBm IP3O using LS LO
9.7 dB NF
200 Ω output impedance
Wide flat performance IF BW
Drives ADC directly for DPD applications
Low Power Consumption
5x5 20 pin package
The F1763 single channel device is designed to operate
with a single 5V supply. It is optimized for operation in
a Multi-mode, Multi-carrier BaseStation Receiver for
frequency bands from 2000MHz - 2900MHz using
either lowside or highside LO. IF frequencies from
50MHz to 500MHz are supported. Nominally, the
device offers +42 dBm Output IP3 with 200mA of ICC.

COMPETITIVE ADVANTAGE
DEVICE BLOCK DIAGRAM
RF
In typical basestation receivers, the RF to IF mixer
dominates the linearity performance for the entire
receive system. The Zero-DistortionTM family of mixers
dramatically improve the maximum signal levels (IM3
tones) that the BTS can withstand at a desired Signal to
Noise Ratio (SNR.) Zero-DistortionTM technology allows
realization of either benefit. In basestation transmitters,
digital pre-distortion (DPD) is employed to improve the
Transmitter performance. By utilizing an ultra-linear
mixer in the DPD RX path, such as the IDTF1763, the
ACLR and/or power consumption of the full Tx system
can be improved significantly. This is because the F1763
can directly drive an ADC through an Anti-Alias filter.
Downstream amplification is not necessary in the DPD
application.
