General Description
The MAX2420/MAX2421/MAX2422/MAX2460/MAX2463
are highly integrated front-end ICs that provide the lowest
cost solution for cordless phones and ISM-band radios
operating in the 900MHz band. All devices incorporate
transmit and receive image-reject mixers to reduce filter
cost. They operate with a +2.7V to +4.8V power supply,
allowing direct connection to a three-cell battery stack.
The receive path incorporates an adjustable-gain LNA
and an image-reject downconverter with 35dB image
suppression. These features yield excellent combined
downconverter noise figure (4dB) and high linearity with
an input third-order intercept point (IP3) of up to +2dBm.
The transmitter consists of a variable-gain IF amplifier
with more than 35dB control range, an image-reject
upconverter with 35dB image rejection, and a power-
amplifier (PA) predriver that produces up to +2dBm (in
some applications serving as the final power stage).
All devices include an on-chip local oscillator (LO),
requiring only an external varactor-tuned LC tank for
operation. The integrated divide-by-64/65 dual-modulus
prescaler can also be set to a direct mode, in which it
acts as an LO buffer amplifier. Four separate power-
down inputs can be used for system power manage-
ment, including a 0.5μA shutdown mode. These parts
are compatible with commonly used modulation
schemes such as FSK, BPSK, and QPSK, as well as fre-
quency hopping and direct sequence spread-spectrum
systems. All devices come in a 28-pin SSOP package.
For applications using direct VCO or BPSK transmit mod-
ulation, as well as receive image rejection, consult the
MAX2424/MAX2426 data sheet. For receive-only devices,
refer to the MAX2440/MAX2441/MAX2442 data sheet.
