2 WARNINGS
Mini-Circuits’ HPA-272+ is designed with multiple levels of protection to prevent injury to the
user and damage to the amplifier during operation. However, Mini-Circuits strongly
recommends that you observe standard operating precautions for high-power RF amplifiers to
reduce the risk of injury and damage to the amplifier and connected components.
2.1 Safety Hazards
Electrical Danger
This equipment contains live 85-265V contacts and should be
used and handled only by qualified professionals. When
performing any activity in and around the HPA-272+ case,
please exercise extreme caution to avoid touching any parts
where live voltage may be present to prevent injury or death
due to electrical shock.
Heavy Object
The equipment case for your HPA-272+ unit is heavy. When
handling, use caution to prevent damage to the equipment
and injury. Always follow safe lifting protocols and use any
necessary lifting aids to prevent muscle strain or back injury.
The unit must be supported in a rack structure by securely
fastened side rails or shelving.
High Speed Fan
Blade
The HPA-272+ contains cooling fans with rotating blades
that can cause serious injury or cut. Remove any loose
articles before working inside the HPA-272+ chassis to
avoid getting caught in moving machinery.

2.2 Additional Precautions
Maximum Input Power
:
The HPA-272+ has a maximum RF input power rating of
+7dBm. Exceeding this maximum will likely cause permanent damage to the amplifier.
Power Supply:
Do not apply RF input signal to the HPA-272+ while the AC mains supply
is disconnected or the amplifier is powered off from the front panel switch. Use only the supplied
AC mains power supply lead for connection to a properly grounded 85-265V mains power
socket.
Air Flow:
The equipment chassis must be mounted by the customer to maintain a
minimum of 1U (1.75”) free air space above and below the top and bottom panels with
unobstructed access to room ambient airflow for proper operation.
Electrostatic Discharge:
Any person operating this unit must have Electrostatic Discharge
(ESD) protection to prevent damage to any components.
Opening & Tampering:
This equipment is designed to be serviced only by professional
electrical technicians. Case openings by any person other than qualified personnel authorized by
Mini-Circuits or the customer will void any and all terms of the Limited Warranty.1
1Although top and bottom panels are intended to allow accessibility, it is important to use caution when connecting or
disconnecting any electrical or RF connection, or when moving, removing, or replacing any wires, cables, connections, or
components within the chassis to avoid potentially damaging or dislodging any other cables or connections.

3 PHYSICAL DESCRIPTION
Mini-Circuits’ HPA-272+ high power amplifier comes housed in an aluminum alloy chassis
measuring 19” wide x 5.20” (3U) high x 20” deep (482 x 132 x 508mm). The front panel is fitted
with an AC power on/off switch, N-Type connectors at the RF input and output ports, a standard
9-pin D-sub socket (see
section 8.2.2
Status Monitoring Via the 9-Pin D-Sub Connector), and 3
LED lights indicating AC power connection (green), temperature alarm (red), and fan
malfunction alarm (red). The front panel of the unit is also equipped with two handles and
marking with the name, model number, frequency range, and saturated output power of unit.
Slotted holes on the outer left and right extensions of the front panel allow secure mounting to a
standard 19” (483mm) rack support structure.
Figure 1: Front panel of HPA-272+ equipment chassis
On the rear panel of the unit is the input for a standard 85-265V AC power supply with caution
label (right side). At the right of the rear panel is a clearly marked grounding terminal. It is
recommended that this terminal be connected to a Common Bonding Network (CBN). On the
left side of the rear panel is an identification sticker containing the model name and serial
number. Two cooling fans are mounted to the center of the panel.

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.
