Description
The SKY73009-11 is an integrated, broadband, high-dynamic
range quadrature demodulator for use in various wireless
communication system applications. The SKY73009-11 can
perform quadrature demodulation of RF input signals from 400 to
3000 MHz directly to baseband frequencies. The quadrature
outputs are differential and can be directly connected to most
commonly available A/D converters.
The high dynamic range and second order input intercept point
(IIP2) value of the SKY73009-11 make it ideal for use in direct
conversion and low intermediate frequency (IF) receivers.
Figure 1 shows a functional block diagram for the SKY73009-11.
The device package and pinout for the 32-pin RF Land Grid Array
(RFLGA) are shown in Figure 2.

Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY73009-11 are provided
in Table 2. The recommended operating conditions are specified
in Table 3. Electrical specifications are provided in Table 4.
Equivalent Input Circuits
An equivalent circuit for the RF input of the SKY73009-11 is
shown in Figure 3. The equivalent circuit for the Local Oscillator
(LO) input is shown in Figure 4. An internal balun is used to
convert the single-ended LO input into a differential signal before
being buffered inside the device.

1 Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters
set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
ESD HANDLING:
Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device.
This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce
potentials of several kilovolts on the human body or equipment, which can discharge without detection.
Industry-standard ESD handling precautions should be used at all times.
