SKY73085-11: 390 – 500 MHz High Gain and Linearity

Diversity Downconversion Mixer for 2G/3G Base Station

Transceiver Applications

Applications

Description

The SKY73085-11 is a fully integrated diversity mixer that

includes Local Oscillator (LO) drivers, an LO switch, high linearity

mixers, and large dynamic range Intermediate Frequency (IF)

amplifiers. Low loss RF baluns have also been included to reduce

design complications and lower system cost.

• 2G/3G base station transceivers:

− GSM/EDGE, CDMA, UMTS/WCDMA

• Land mobile radio

• ISM band transceivers

• High performance radio links

• RF identification

The SKY73085-11 features an input IP3 of 24.9 dBm and a Noise

Figure (NF) of 9.3 dB, making the device an ideal solution for high

dynamic range systems such as 2G/3G base station receivers.

The LO switch provides more than 60 dB of isolation between LO

inputs and supports the switching time required for GSM/EDGE

base stations.

Features

• Operating frequency range: 390 to 500 MHz

• IF frequency range: 50 to 250 MHz

• Conversion gain: 9.3 dB

The SKY73085-11 is manufactured using a robust silicon BiCMOS

process and has been designed for optimum long-term reliability.

The SKY73085-11 diversity downconversion mixer is provided in

a compact, 36-pin Multi-Chip Module (MCM). A functional block

diagram is shown in Figure 1. The pin configuration and package

are shown in Figure 2. Signal pin assignments and functional pin

descriptions are provided in Table 1.

• Input IP3: 24.9 dBm

• Output IP3: 34.2 dBm

• Noise figure: 9.3 dB

• Integrated LO drivers

• Integrated low loss RF baluns

• High linearity IF amplifiers
