1 14-22 MHz F12NBGI GENERAL DESCRIPTION This document describes the specifications for the IDTF12 Zero-Distortion TM RF to IF Downconverting Mixer. This device is part of a series of mixers offered with high side or low side injection options for all UTRA bands. See the Part# Matrix for the details of all devices in this series. The F12 dual 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 RF bands from 1-22 MHz with Low Side Injection or from 14 to 1 MHz with High Side Injection. IF frequencies from 5 to MHz are supported. Nominally, the device offers +43 dbm Output IP3 with 32 ma of I CC. Alternately one can adjust 4 resistor values and a toggle pin to run the device in low current mode with +4 dbm Output IP3 and 232 ma of I CC. COMPETITIVE ADVANTAGE FEATURES Dual Path for Diversity Systems Ideal for Multi-Carrier Systems.5 db Gain Ultra linear +43 dbm IP3 O Low NF < 1 db 2 Ω output impedance Ultra high +13 dbm P1dB I Pin Compatible w/existing solutions 6x6 36 pin package Power Down mode < 2 nsec settling from Power Down Minimizes Synth pulling in Standby Mode Low Current Mode : I CC = 232 ma Standard Mode: I CC = 32 ma NOTE production BOM on p. 2 DEVICE BLOCK DIAGRAM 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.) Alternately, one can run the device in Low Current Mode to reduce Power consumption significantly. Zero-Distortion TM technology allows realization of either benefit.
