RF to IF Single Downconverting Mixer
GENERAL DESCRIPTION
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 ICC.
COMPETITIVE ADVANTAGE
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 (IM₃
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.
 IP3_O:  9 dB
 Dissipation:  10%
 Allows for higher RF gain
improving Sensitivity
 Eliminates the need for an
ADC driver or IF VGA in DPD
linearization path
