RMBA09501-58 - Cellular 2 Watt Linear GaAs
RF Components MMIC Power Amplifier
ADVANCED INFORMATION
Description
The RMBA09501-58 is a highly linear Power Amplifier. The two stage circuit uses Raytheon RF
Components’ pHEMT process. It is designed for use as a driver stage for Cellular base stations, or as
the output stage for Micro- and Pico-Cell base stations. The amplifier has been optimized for high
linearity requirements for CDMA operation.
Features
! 2 Watt Linear output power at 36 dBc ACPR1 for CDMA
operation

Notes:
1. Only under quiescent conditions – no RF applied.
2. VDD = 7.0V, Tc = 25°C. Part mounted on evaluation board with input and output matching to 50 Ohms.
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. VG1 and VG2 must be individually adjusted to achieve IDQ1 and IDQ2. A single VGG bias supply adjusted to achieve
IDQTOTAL=550mA can be used with nearly equivalent performance. Values for IDQ1 and IDQ2 shown have been
optimized for CDMA operation. IDQ1 and IDQ2 (or IDQTOTAL) can be adjusted to optimize the linearity of the amplifier for
other modulation systems.
5. 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.
The device requires external input and output matching to 50 Ohms as shown in Figure 3 and the Parts
List.
