RMBA19500A
PCS1900 2 Watt GaAs MMIC Power Amplifier
General Description
The RMBA19500A is a highly linear Power Amplifier. The
two stage circuit uses our pHEMT process. It has been
designed for use as a driver stage for PCS1900 base
stations, or as the output stage for Micro- and Pico-Cell
base stations. The amplifier has been optimized for high
linearity requirements for PCS operation.

.
3. 9 Channel Forward Link QPSK Source; 1.23 Mbps modulation rate. CDMA ACPR1 is measured using the ratio of the average power within the 1.23 MHz channel
at band center to the average power within a 30 KHz bandwidth at an 885 KHz offset. Minimum CDMA output power is met with ACPR1 > 36 dBc.
4. OIP3 specifications are achieved for power output levels of 27 and 30 dBm per tone with tone spacing of 1.25 MHz at band-center with adjusted supply and bias
conditions of Vdd = 6.5V and IdqTotal = 625mA (see Note 5).
5. VG1,2 and VG3 must be individually adjusted to achieve IDQ1,2 and IDQ3. A single VGG bias supply adjusted to achieve IDQTOTAL = 625mA can be used with
nearly equivalent performance. Values for IDQ1,2 and IDQ3 shown have been optimized for CDMA operation. IDQ1, 2 and IDQ3 (or IDQTOTAL) can be adjusted
to optimize the linearity of the amplifier for other modulation systems.
The device requires external input and output matching to 50
