Skyworks SKY73212-11 is a fully integrated diversity downconverter that includes a high linearity mixer, large dynamic range Intermediate Frequency (IF) amplifier, and a complete Voltage Controlled Oscillator (VCO), synthesizer, and Local Oscillator (LO) chain. Low loss RF baluns have also been included to reduce design complications and to lower system cost. The SKY73212-11 features a 3rd Order Input Intercept Point (IIP3) of +24 dBm and a Noise Figure (NF) of 11 dB, which make the device an ideal solution for high dynamic range systems such as 2G/3G base station receivers. The SKY73212-11 also includes a fully integrated wideband VCO/Integer-N frequency synthesizer. By applying internal VCO division, the output LO frequency can be set to the desired value while minimizing the phase noise. The SKY73212-11 is controlled by a Serial Peripheral Interface (SPI) and is manufactured using a robust silicon BiCMOS process. The device has been designed for optimum long-term reliability. It is manufactured in a compact, 44-pin 10 x 6 mm Multi-Chip Module (MCM).
