MAX2511
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.
For applications using in-phase (I) and quadrature (Q)
baseband architecture for the transmitter, Maxim offers
a corresponding transceiver product: the MAX2510.
The MAX2510 has features similar to those of the
MAX2511, but upconverts I/Q baseband signals using
a quadrature upconverter.

Note 1:Guaranteed by design and characterization.
Note 2:Driving RXIN or RXINwith a power level greater than the 1dB compression level forces the input stage out of its linear
range, causing harmonic and intermodulation distortion. The RSSI output increases monotonically with increasing input
levels beyond the mixer’s 1dB compression level.
Note 3:Assuming the supply voltage has been applied, this includes settling of the limiter offset correction and the Rx or Tx bias
stabilization time. Guaranteed by design.
Note 4:LIMOUT, LIMOUTloaded with 2kWdifferential. With no load, the output swing is approximately twice as large.
Note 5:The RSSI maximum intercept is the maximum input power (over a statistical sample of parts) at which the RSSI output is 0V.
This point is extrapolated from the linear portion of the RSSI voltage versus limiter input power. This specification and the
RSSI slope define the ideal behavior of the RSSI function (the slope and intercept of a straight line), while the RSSI relative
error specification defines the deviations from this line. See the RSSI Output Voltage vs. Limiter Input Power graph in the
Typical Operating Characteristics.
Note 6:The RSSI relative error is the deviation from the best-fitting straight line of RSSI output voltage versus limiter input power.
A 0dB relative error is exactly on this line. The limiter input power range for this test is -75dBm to +5dBm from 50W. See the
RSSI Relative Error graph in the Typical Operating Characteristics.
Note 7:Operation outside this frequency range is possible but has not been characterized. At lower frequencies, it might be
necessary to overdrive the oscillator with an external signal source.
Note 8:If a larger output level is required, a higher value of load resistance (up to 100W) may be used.
Note 9:This assumes that the supply voltage has been applied, and includes the settling time of VREF, using the Typical
Operating Circuit.
Note 10:Using two tones at 10.7MHz and 10.8MHz, 50mVp-p per tone at TXIN, TXIN. See Typical Operating Characteristics.
