Example 8.2: PMA-5453 MMIC
The second example uses a Mini-Circuits PMA-5453+ E-PHEMT MMIC. The IC is
designed as a low noise front-end amplifier for a wide range of applications like Cellular
Radio, Mobile Phone, and WLAN. The IC has a bandwidth of 50 MHz to 6 GHz, operates
at 3 V, has a NF of 0.6 dB, and is a relatively low cost device. This amplifier draws a lot
more supply current than the BGB707, but it has a 9 dB higher 1 dB compression (OP
1db
)
power output and 20 dB higher third order intercept (OIP3) power level than the BGB707.
The supply current can be set between 30 mA to 80 mA (@25C) by varying a bias
resistor. That will vary the RF performance. Mini-Circuits provides typical S parameter
and measured performance data at different supply voltages, currents and temperatures.
However, Mini-Circuits does not provide an AWRDE linear model like the one for the
BGB707. The S Parameter data can be imported into AWR DE to plot stability.
