4 FUNCTIONAL DESCRIPTION
Mini-Circuits’ HPA-272+ is a high-power rack-mountable RF amplifier capable of delivering
output power up to 100W across the 700 to 2700 MHz frequency range. The amplifier provides
48 dB gain with ±1.7 dB gain flatness, +55 dBm OIP3 and 89 dB reverse isolation. It operates
on a self-contained 85 – 265V AC line power supply. This model features internal cooling and
self-protection against over-temperature, and is immune to open and short loads while
delivering full power from the output port.
The unit features LED indicators on the front panel which illuminate to alert the user when AC
power is connected, when the unit temperature exceeds the maximum rating, and when the
cooling fans are not functioning properly. The 9-Pin D-Sub socket allows remote monitoring of
these conditions in layouts where the front panel is not clearly visible to the operator.
The HPA-272+ is an ideal solution for test applications requiring high power over a wide
frequency range such as EMI and antenna testing, RF power stress testing, reliability testing
and more. It is also highly useful for production test applications in which it is desirable to test
many DUTs in parallel such as HTOL. The amplifier can be paired with high power splitters to
distribute a test signal through up to 80 channels. See section 9 for more information about
applications of this equipment.
