SKY73208-11中文资料350-5000 MHz Wideband Receive Mixer with Integrated Integer-N PLL and VCO数据手册Skyworks规格书

描述 Description

Please note: SKY73208-11 is being discontinued and is not recommended for new designs.

Skyworks SKY73208-11 is a fully integrated wideband receive downconverter that includes a high linearity mixer and a complete Voltage Controlled Oscillator (VCO), synthesizer, and Local Oscillator (LO) chain. A low loss RF balun has also been included to reduce design complications and to lower system cost.

The SKY73208-11 features a 3rd Order Input Intercept Point (IIP3) of +26 dBm and a Noise Figure (NF) of 14 dB, which make the device an ideal solution for high dynamic range systems such as 2G/3G base station receivers.

The SKY73208-11 also includes a fully integrated wideband VCO/Integer-N frequency synthesizer. The device includes four differential VCOs that cover the output frequency range from 2.8 GHz to 6.0 GHz. By applying internal VCO division, the output LO frequency can be set to the desired value while minimizing the phase noise. The direct, non-divided internal VCO frequency can also be monitored at the bidirectional VCO pins.

The flexible SKY73208-11 LO configuration allows the loop to be locked by an external VCO or external Phase Locked Loop (PLL), or the device can use the divider chain only. The SKY73208-11 is controlled by a Serial Peripheral Interface (SPI).

The SKY73208-11 is manufactured using a robust silicon BiCMOS process and has been designed for optimum long-term reliability. It is manufactured in a compact, 36-pin 6 x 6 mm Multi-Chip Module (MCM).
