ESCRIPTION
This document describes the specifications for the
IDTF1751 Zero-Distortion
TM
Midband 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.
The F1751 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 over
the frequency range from 1400MHz to 2500MHz using
either lowside or highside LO. IF frequencies from
50MHz to 500MHz are supported. Nominally, the
device offers +43dBm Output IP3 using HS LO or
+37.5dBm using LS LO with 190mA of I
CC
.

DVANTAGE
In typical basestation receivers, the RF to IF mixer
dominates the linearity performance for the entire
receive system. The Zero-Distortion
TM
family of mixers
dramatically improve the maximum signal levels (IM
3
tones) that the BTS can withstand at a desired Signal to
Noise Ratio (SNR.) Zero-Distortion
TM
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 IDTF1751, the
ACLR and/or power consumption of the full Tx system
can be improved significantly. This is because the F1751
can directly drive an ADC through an Anti-Alias filter.
Downstream amplification is not necessary in the DPD
application.
