Description

The 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 third 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). A functional block diagram is shown in Figure 1.

The pin configuration and package are shown in Figure 2. Signal
