Complete 450MHz Quadrature Transmitter
General Description
The MAX2370 integrated quadrature transmitter is
designed for 450MHz applications. The device takes a
differential I/Q baseband input and converts it up to
intermediate frequency (IF) through a quadrature modu-
lator and IF variable-gain amplifier (VGA). The signal is
then routed to an external IF filter and upconverted to RF
through an image-reject mixer and RF VGA. The signal
is further amplified with an on-chip power amplifier (PA)
driver. An IF synthesizer, an RF synthesizer, a local
oscillator buffer, and an SPI?/QSPI?/MICROWIRE?-
compatible, 3-wire programmable bus complete the
basic functional blocks of this IC.
The MAX2370 is available in a 48-pin TQFN package
with exposed paddle and is specified for the extended
temperature range (-40°C to +85°C).
