GENERAL DESCRIPTION
The ADF9010 is a fully integrated RF Tx modulator and Rx
analog baseband front end that operates in the frequency
range from 840 MHz to 960 MHz. The receive path consists
of a fully differential I/Q baseband PGA, low-pass filter, and
general signal conditioning before connecting to an Rx ADC
for baseband conversion. The Rx LPF gain ranges from 3 dB
to 24 dB, programmable in 3 dB steps. The Rx LPF features
four programmable modes with cutoff frequencies of 330 kHz,
880 kHz, and 1.76 MHz, or the filter can be bypassed if necessary.

The transmit path consists of a fully integrated differential Tx
direct I/Q upconverter with a high linearity PA driver amplifier.
It converts a baseband I/Q signal to an RF carrier-based signal
between 840 MHz and 960 MHz. The highly linear transmit
signal path ensures low output distortion.
Complete local oscillator (LO) signal generation is integrated
on chip, including the integer-N synthesizer and VCO, which
generate the required I and Q signals for transmit I/Q upconver-
sion. The LO signal is also available at the output to drive an
external RF demodulator. Control of all the on-chip registers
is via a simple 3-wire serial interface. The device operates with a
power supply ranging from 3.15 V to 3.45 V and can be powered
down when not in use.
