_______________General Desc ription
The MAX2402 transmitter integrates a double-balanced
mixer, buffered local oscillator (LO) port, variable gain
stage, and power amplifier into a single IC. It is intend-
ed for use in the 800MHz to 1000MHz band, and is
compatible with both direct-sequence and frequency-
hopping spread-spectrum designs in the 902MHz to
928MHz ISM band.
In a typical application, a digital baseband signal is
mixed with a local oscillator signal to yield a BPSK-
modulated carrier at the antenna. Alternatively, the
baseband input may be grounded and an FSK-
modulated LO signal applied directly to the LO port.
The LO port consists of a limiting amplifier that can
accept a single-ended or differential signal with input
power between -6dBm and +6dBm in the 800MHz to
1000MHz frequency range. The baseband modulation
input is linear over a 2V range, and limits with larger
signal levels within the supply range. The double-
balanced mixer has been optimized for high carrier
rejection. The variable gain stage offers typically 40dB
of adjustment range. The power amplifier provides
more than 20dBm output power and has a bias adjust-
ment, which allows adjustment of efficiency and
harmonic distortion.
A shutdown function reduces the current draw to less
than 2μA in less than 10μs. The MAX2402 comes in a
20-pin SSOP package to minimize board area.
