MAX2314
The MAX2314 supports CDMA cellular-band, dual-
mode operation. As with the MAX2310, the FM mode
can be configured for conversion to the I port or quad-
rature conversion to both the I and Q ports (Figure 3).
The MAX2314’s operational modes are described in
Table 3. These modes are set by programming the
control register and setting logic levels on control pins.
__________Applications Information
Variable-Gain Amplifier and Demodulator
The MAX2310 family provides a Variable-Gain Amplifier
(VGA) with exceptional gain range. The MAX2310/
MAX2314 support multimode applications with dual dif-
ferential inputs, selectable with the IN_SEL (IS) control
bit. On the MAX2310 this function can be controlled
with the MODE pin, which overrides the IS control bit.
The VGA’s gain is controlled over a 110dB range with
MAX2314
