RMPA5252
4.9–5.9 GHz InGaP HBT WLAN Linear Power Amplifier
Features
General Description
■ Full 4.9 to 5.9GHz operation
The RMPA5252 power amplifier is designed for high
performance WLAN applications in the 4.9–5.9 GHz frequency
band. The low profile 16 pin 3 x 3 x 0.9 mm package with internal
matching on both input and output to 50 Ohms minimizes next
level PCB space and allows for simplified integration. An on-chip
detector provides power sensing capability. The PA’s low power
consumption and excellent linearity are achieved using our
InGaP Heterojunction Bipolar Transistor (HBT) technology.
■ 34dB small signal gain
■ 3% EVM at 18dBm modulated power out
■ 3.3V single positive supply operation
■ Integrated power detector with 20dB dynamic range
■ Lead-free RoHS compliant 3 x 3 x 0.9 mm leadless package
■ Internally matched to 50 Ohms and DC blocked RF input/
output
■ Optimized for use in 802.11a applications

Evaluation Board Turn-On Sequence
Recommended turn-on sequence:
1) Connect common ground terminal to the Ground (GND) pin
on the board.
6) Apply input RF power to SMA connector pin RFIN. Current
for pin VCC will vary depending on the input drive level.
2) Connect voltmeter to DT1 pin (Detector Voltage).
7) Vary positive voltage VM12, VM34 from +2.4 V to +0 V to shut
down the amplifier or alter the power level. Shut down current
flow into the pins:
3) Connect VC1, VC2, VC3, VC4 (Collector voltages) together
using jumper cables. Apply a single positive supply voltage
(3.3V) to pin VC4.
Pin
Current
4) Connect VM12 and VM34 (Power Control voltage) together
using a jumper cable. Apply a single positive supply voltage
(2.4V) to pin VM12.
VCC (total)
<1 nA
Recommended turn-off sequence:
Use reverse order described in the turn-on sequence above.
Note:
5) At this point, you should expect to observe the following posi-
tive currents flowing into the pins::
