Dual Path for Diversity Systems
Ideal for MultiꢀCarrier Systems
9.0 dB Gain
This document describes the specifications for the
IDTF1102 ZeroꢀDistortionTM RF to IF Downconverting
Mixer. This device is part of a series of downconverting
mixers covering all UTRA bands. See the Part# Matrix
for the details of all devices in the series.
Ultra linear:
ꢁ +43 dBm IP3O (STD Mode)
ꢁ +36 dBm IP3O (LC Mode)
Low NF < 10 dB
Extended LO level range for MIMO (ꢀ6 dBm)
200 ꢁ output impedance
Ultra high +13 dBm P1dBI
Pin Compatible with existing solutions
6x6 36 pin package
The F1102 dual channel device operates with a single
5V supply. It is optimized for operation in a Multiꢀ
carrier BaseStation Receiver for RF bands from 698 to
915 MHz with High or Low Side Injection. IF
frequencies from 50 to 300 MHz are supported. The
F1102 also supports the 400 MHz RF bands with some
simple external matching modifications (see page 25).
Nominally, the device offers +43 dBm Output IP3 with
330 mA of ICC. Alternately one can adjust 4 resistor
values and a toggle pin to run the devices in low
current mode (LC mode) with +36 dBm Output IP3
and 235 mA of ICC.

< 200 nsec settling from Power Down
Minimizes Synth pulling in Standby Mode
Low Current Mode : ICC = 235 mA
Standard Mode: ICC = 330 mA
COMPETITIVE ADVANTAGE
DEVICE BLOCK DIAGRAM
In typical basestation receivers the mixer limits the
linearity performance for the entire receive system. The
F1102 with ZeroꢀDistortion technology dramatically
improves the maximum IM3 interference that the BTS
can withstand at a desired Signal to Noise Ratio (SNR.)
Alternately, one can run the device in LC Mode to reduce
Power consumption significantly.
