Each driver takes its input from the upconverter after passing
through an image reject filter. The drivers amplify the signal and
send it to an external power amplifier.
Technical Description
The RF25F is an upconverter and driver amplifier used by the
CDMA transmitter section in the cellular and PCS bands. Its
function can also be used in AMPS mode. A band select
command chooses between the cellular and the PCS band. A
mode select command chooses between CDMA and AMPS
mode in the cellular band. The ASIC consists of two variable
gain upconverters and two power amplifier drivers for the
cellular and PCS bands.
The DRIVER_ON command is used during gated output power
mode to deactivate the drivers in periods of no transmission. A
Surface Acoustic Wave (SAW) filter for noise and image
rejection should be placed between the driver and the external
power amplifier.
Electrical and Mechanical Specifications
Upconverters. The cellular and PCS variable gain upconverters
receive the IF signal. Each upconverter uses an external Local
Oscillator (LO) controlled by an external Phase Locked Loop
(PLL). Upconverter conversion gain control can be used to
calibrate out part-to-part and temperature gain variations in the
transmit path. A band select command switches between the
cellular and PCS bands. The DRIVER_ON command
deactivates the driver during no transmission status. The output
RF signal is sent to an output pin to be filtered before driver
amplification.
Signal pin assignments and functional pin descriptions are
described in Table 1. The absolute maximum ratings of the
RF25F are provided in Table 2. The recommended operating
conditions are specified in Table 3 and electrical specifications
are provided in Table 4.
Typical performance characteristics of the RF25F are illustrated
in Figures 3 through 26. Figure 27 provides a typical application
schematic diagram. Figure 28 shows the package dimensions
for the 32-pin LGA and Figure 29 provides the tape and reel
dimensions.
Power Amplifier Drivers. Two power amplifier drivers are
included, the cellular driver and the PCS driver.
