SKY73021: 1700 – 2200 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, PHS Land mobile radio Wireless Local Loop High performance radio links Private mobile radio
Description
The SKY73021 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 SKY73021 features an input IP3 of 26.0 dBm and a Noise Figure (NF) of 9.6 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 50 dB of isolation between LO inputs and supports the switching time required for GSM/EDGE base stations. The SKY73021 is manufactured using a robust silicon BiCMOS process and has been designed for optimum long-term reliability. The SKY73021 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.
