SKY73212-11: 1700-2000 MHz Diversity Downconversion

Mixer with Integrated Integer-N PLL and VCO

Applications

Description

Skyworks SKY73212-11 is a fully integrated diversity

• Cellular base station systems: GSM/EDGE, CDMA2000, WCDMA,

TD-SCDMA

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 3^rdOrder 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.

• Other wireless communication systems

Features

• RF frequency range: 1700 to 2000 MHz

• IF frequency range: 40 to 300 MHz

• Conversion gain: 9 dB

• IIP3: +24 dBm; OIP3: +33 dBm

• Noise Figure: 11 dB

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.

• Integrated RF balun

• High linearity IF amplifier

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). 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.

• Integer-N frequency synthesizer

• Low phase-noise VCO

• Low RF output comparison spurs

• Programmable 18-bit N-counter and 11-bit R-counter

• Wide range of reference frequencies

• Programmable charge pump currents

• Flexible configuration that allows connection to an external VCO

or PLL

• Digital lock detector

• Optional adjustment of the core, divider, and charge pump

currents by external resistor

• Power supply for mixer: 5 V; power supply for synthesizer: 3.3 V

• Small, low-cost MCM (44-pin, 10 x 6 mm) SMT package (MSL3,

260 °C per JEDEC J-STD-020)
