W-CDMA/W-TDD/TD-SCDMA Zero-IF Receivers
Synthesizer and LO Generation
The MAX2390–MAX2393, MAX2401 incorporate an inte-
ger-N synthesizer on-chip, including the VCO, tank, all
dividers, phase comparator, etc. Only a TCXO and a
loop filter are required as external components. The LO
leakage at the LNA input is minimized by running the
internal VCO at 2x the desired LO frequency. The typical
application uses a comparison frequency of 200kHz—
the channel raster for 3GPP-FDD and -TDD systems.
There are no special requirements for the synthesizer
loop filter. The EV kits use a classic Type-II loop filter,
The MAX2396/MAX2400 integrate the VCO and the
divide-by-2 for the LO generation, but do not include
the synthesizer. The LO leakage at the LNA input is
minimized by running the VCO at twice the desired RF
frequency. The VCO signal is made available to the
external PLL through an on-chip divide-by-three
prescaler. Since f VCO_OUTPUT = f VCO / 3, and f RFLO =
f VCO / 2, then f VCO_OUTPUT = (2/3)f RFLO . That is, when
the RFLO of the MAX2400 is running at midband
(1960MHz), the VCO output and the synthesizer are
running at 1306.67MHz.
with a bandwidth of about 20kHz. This ensures a 200μs
settling time for a 60MHz frequency jump.
Use a 1nF DC-blocking capacitor in series with the ref-
erence oscillator input so as not to disturb the DC bias.
