Direct-Conversion Tuner ICs for Digital DBS Applications
General DescriptionThe MAX2102/MAX2105†are low-cost direct-conver-
sion tuner ICs designed for use in digital direct-broad-
cast satellite (DBS) television set-top box units. The
direct-conversion architecture reduces system cost
compared to devices with IF-based architectures.
The MAX2102/MAX2105 directly tune L-band signals to
baseband using a broadband I/Q downconverter.
Operating frequency range spans from at least 950MHz
to 2150MHz.
The ICs include a low-noise amplifier (LNA) with auto-
matic gain control (AGC), two downconverter mixers,
an oscillator buffer with 90°quadrature generator and
prescaler, and baseband amplifiers.
The MAX2102 features an AGC range of 50dB, allowing
input power levels as low as -69dBm. The MAX2105
has a reduced AGC range of 41dB and accepts input
power levels down to -60dBm. The reduced AGC range
of the MAX2105 allows the use of a high-gain external
LNA to achieve a lower system noise figure (NF).

Note 1:All specifications with guaranteed min/max limits are met within this frequency range. Contact factory for
MAX2102/MAX2105 versions with expanded frequency range.
Note 2:Guaranteed by production test and/or design and characterization.
Note 3:Guaranteed by design and characterization.
Note 4:IOUT, QOUT Phase and Amplitude Imbalance specifications are met within this LO power range.
Note 5:Tested under two conditions: 1) Normal test: PRFIN= -20dBm, and 2) Overdrive test: PRFIN= -5dBm but AGC set via servo
loop for VIOUT= VQOUT= 0.5Vp-p for PRFIN= -30dBm.
Note 6:Negative numbers (-0.1°) indicate improvement in quadrature accuracy with increasing temperature.
Note 7:Includes contribution from front-end gain tilt and delay variations produced by varying fRFINby ±30MHz.
Note 8:1kHz minimum frequency determined by 0.22µF offset-correction capacitors. Different value capacitors yield proportionally
different low-frequency cutoffs. Group delay at low frequencies will also be affected. See Applications Informationsection.
