PRODUCT DESCRIPTION
This quad band power amplifier module is designed
to support dual, tri and quad band applications. The
module includes an integrated power control
scheme that facilitates fast and easy production
calibration and reduces the number of external
components required to complete a power control
function.
The amplifiers power control range is typically
55 dB, with the output power set by applying an
analog voltage to V
RAMP
. The logical control inputs,
V CC2
DCS/PCS
TX_EN and BS, are both 1.8 V and 3 V logic
compliant. The TX_EN is used to enable the
amplifier typically with the TX burst. The BS is used
to select which amplifier is enabled.
There are two amplifier chains, one to support
GSM850/900 bands, the other for DCS/PCS bands.
All of the RF ports for this device are internally
matched to 50
W.
Internal DC blocks are provided at
the RF ports.
