Low-Voltage IF Transceiver
with Limiter and RSSI
_______________General Description
The MAX2511 is a complete, highly integrated IF trans-
ceiver for applications employing a dual-conversion
architecture. Alternatively, the MAX2511 can be used
as a single-conversion transceiver if the RF operating
frequency ranges from 200MHz to 440MHz.
In a typical application, the receiver downconverts a
high IF/RF (200MHz to 440MHz) to a 10.7MHz low IF
using an image-reject mixer. Functions include an
image-reject downconverter with 34dB of image sup-
pression followed by an IF buffer that can drive an off-
chip IF filter; an on-chip limiting amplifier offering 90dB
of monotonic received-signal-strength indication (RSSI);
and a robust limiter output driver. The transmit image-
reject mixer generates a clean output spectrum to mini-
mize filter requirements. It is followed by a 40dB
variable-gain amplifier that maintains IM3 levels below
-35dBc. Maximum output power is 2dBm. A VCO and
oscillator buffer for driving an external prescaler are
also included.
The MAX2511 operates from a 2.7V to 5.5V supply and
includes flexible power-management control. Supply
current is reduced to 0.1μA in shutdown mode.
