www.DataSheet4U.com PRELIMINARY DATA SHEET SKY73020: 700 – 1000 MHz High Gain and Linearity Diversity Downconversion Mixer for 2G/3G Base Station Transceiver Applications Applications 2G/3G base station transceivers: − GSM/EDGE, CDMA, UMTS/WCDMA, iDEN Land mobile radio ISM band transceivers High performance radio links RF identification Description The SKY73020 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. The SKY73020 features an input IP3 of 27.0 dBm and a Noise Figure (NF) of 10.2 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 65 dB of isolation between LO inputs and supports the switching time required for GSM/EDGE base stations. The SKY73020 is manufactured using a robust silicon BiCMOS process and has been designed for optimum long-term reliability. The SKY73020 diversity downconversion mixer is provided in a compact, 36-pin 6 x 6 mm 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. Features Operating frequency range: 700 to 1000 MHz IF frequency range: 50 to 250 MHz Co...
