Low-Voltage IF Transceiver with Limiter RSSI and Quadrature Modulator
________________General DescriptionThe MAX2510 is a highly integrated IF transceiver for
digital wireless applications. It operates from a +2.7V to
+5.5V supply voltage and features four operating
modes for advanced system power management.
Supply current is reduced to 0.2µA in shutdown mode.
In a typical application, the receiver downconverts a
high IF/RF (up to 600MHz) to a low IF (up to 30MHz)
using a double-balanced mixer. Additional functions
included in the receiver section are an IF buffer that
can drive an off-chip filter, an on-chip limiting amplifier
offering 90dB of received-signal-strength indication
(RSSI), and a robust differential limiter output driver
designed to directly drive a CMOS input. The transmit-
ter section upconverts I and Q baseband signals to an
IF in the 100MHz to 600MHz range using a quadrature
modulator. The transmit output is easily matched to
drive a SAW filter with an adjustable output from 0dBm
to -40dBm and excellent linearity.
The MAX2511 has features similar to the MAX2510, but
upconverts a low IF with an image-reject mixer. The
MAX2511 downconverter also offers image rejection
with a limiter/RSSI stage similar to that of the MAX2510.

Note 4: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. Input 1dB compression point is limited by MIXOUT voltage swing, which
is approximately 2Vp-p into a 165Ωload.
Note 5:Assuming the supply voltage has been applied, this includes limiter offset-correction settling and Rx or Tx bias stabilization
time. Guaranteed by design and characterization.
Note 6:The RSSI maximum zero-scale intercept is the maximum (over a statistical sample of parts) input power at which the RSSI
output would be 0V. This point is extrapolated from the linear portion of the RSSI Output Voltage vs. Limiter Input Power
graph in the Typical Operating Characteristics. This specification and the RSSI slope define the RSSI function’s ideal
behavior (the slope and intercept of a straight line), while the RSSI relative error specification defines the deviations from
this line. See the Typical Operating Characteristicsfor the RSSI Output Voltage vs. Limiter Input Power graph.
Note 7:The RSSI relative error is the deviation from the best-fitting straight line of the RSSI output voltage versus the limiter input
power. This number represents the worst-case deviation at any point along this line. A 0dB relative error is exactly on the
ideal RSSI transfer function. The limiter input power range for this test is -75dBm to 5dBm from 50Ω. See the Typical
Operating Characteristics for the RSSI Relative Error graph.
Note 8:Transmit sideband suppression is typically better than 35dB. Operation outside this frequency range is possible but has
not been characterized.
Note 9:Output IM3 level is typically better than -29dBc.
Note 10:The output power can be increased by raising GC above 2V. Refer to the Transmitter Output Power vs. GC Voltage and
Frequency graph in the Typical Operating Characteristics.
Note 11:Using two tones at 400kHz and 500kHz, 250mVp-p differential per tone at I, I, Q, Q.
