2 WARNINGS

30 lbs. (13.61 Kg)

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

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,

Electrical Danger

Heavy Object

please exercise extreme caution to avoid touching any parts where live voltage may be present to prevent injury or death due to electrical shock.

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

Power Supply:

Air Flow:

Electrostatic Discharge:

Opening & Tampering:

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.

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.

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.

Any person operating this unit must have Electrostatic Discharge

(ESD) protection to prevent damage to any components.

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.

Although top and bot tom panels are intended to allow accessibility, it is important to use caution w hen 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 potenti ally damaging or dislodgi ng any other cables or connections.

section 8.2.2

Figure 1: Front panel of HPA-272+ equipment chassis

Figure 2: Rear panel of HPA-272+ equipment chassis

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 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.

Status Monitoring Via the 9-Pin D-Sub Connector), and 3

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

section 9

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 applications of this equipment.

7.1 Rack Mounting

The HPA-272+ equipment chassis should be fastened to rack support structure through the slotted rack mounting holes (4x) on the front panel shown below.

Chassis must be mounted to maintain a minimum of 1U (1.75”) clearance above top panel

and below bottom panel with unobstructed access to room ambient airflow for proper operation.

Additionally,

. This can be facilitated by side rails or by a shelf, sufficiently secured to a standard, high

grade, 19-inch equipment rack.

7.2 Rear Panel Grounding Terminal

The rear panel of the chassis is constructed with a grounding stud to ground the box. This stud should be connected to a Common Bonding Network (CBN) with 20 gauge or larger copper wire.

8.1 Connecting the Amplifier

The HPA-272+ has been designed with multiple levels of protection to prevent avoidable damage to the amplifier during operation. However, Mini-Circuits’ strongly recommends that standard operating precautions for high-power RF amplifiers be observed to reduce risk of damage to the amplifier and connected components.

The recommended sequence for connecting the amplifier is as follows:

1) Connect AC mains power supply

2) Connect output load

3) Turn on the AC power using the switch on the front panel

4) Apply the RF input signal

8.2 Temperature and Fan Monitoring

The HPA-272+ features LED lights on the front panel which provide easy visual confirmation of the internal temperature and fan status.

• The green LED labelled “Power” indicates the unit is connected to an AC power

supply and powered on.

• The red LED labeled “Temp” indicates an alarm that the temperature inside the

unit exceeds the maximum rating.

• The red LED labeled “Fan” indicates a fault or mechanical blockage with the

cooling fans.

Both of the red LEDs should be off during normal operation.

In situations where the front panel of the amplifier unit is not clearly visible, the internal temperature and the “health” of the cooling fans can also be monitored remotely via the D-Sub connector on the front panel.

Connections to the 9-pin D-Sub socket on the HPA-272+ should be made as shown in table 4 below. The output at pins 1 and 2 will be TTL logic levels indicating the status of the amplifier as follows:

• Logic 1 (high) at pin 1 signals over temperature alarm

• Logic 1 (high) at pin 1 signals fan malfunction and potential mechanical blockage

• Logic 0 (low) at these pins indicates normal operation

9.1 High Power, Multi-Channel Burn-In System

The HPA-272+ may be combined with MiniCircuits signal generator, (100W) 10-way splitter, and splitter rack (containing 10 independent, 10W, 4-way splitters), to deliver a test tone anywhere in the 700 to 2700 MHz range into 40 test channels simultaneously at greater than 1W per channel.

This setup allows dramatic increases in burn-in production test throughput by enabling many DUTs to be tested in parallel.
