Class:
Supply Voltage:
This ultra broadband class A amplier operates from below 1 MHz to over 1 GHz. Using all gold
metallized LDMOS transistors and a stable design, this compact, high performance laboratory amplier
will nd use in many applications.
The LA2-1-1025-33 is offered as a standalone unit requiring the customer to mount to a modest
heat sink, or we offer this with a heat sink. A disable line is option.

Attach amplier to heatsink using thin layer of thermal compound. The amplier will produce approximately 20W of heat, so a
medium size heatsink will be adequate - a heatsink with approximate dimensions 2 x the area of the lab amp and approx 1.0”
deep. A smaller heatsink may be used if any airow is used.
Attach RF Input and RF Output using SMA Female connectors and tighten. Install ground wire and Vsup using solder connections - make sure to attach positive wire to Vsup terminal. If optional disable is ordered, install using disable terminal on input
side of amplier.
To operate, apply Vsup and amplier is ready to operate.

Standard Pallet Options:
SMA Female Connectors, Input and Output. Stainless Body, Gold Center pin, 4-hole SMA bolted to pallet amplier edge through bottom two holes located at ampliers RF IN and RF OUT
locations. All stainless steel hardware.
Enclosure- all aluminum machined enclosure available for most pallet ampliers. Alodyned aluminum, alloy 6061-T6. SMA Female input and output RF connectors. Supply voltage and ground
through solder / feedthrough connections. Module must be bolted to appropriate heatsink.
Heat Sink - aluminum extruded heat sink, black anodized. Pallet amplier or module will be bolted to heatsink. Customer will be required to provide adequate airow.
Heat sink with fan - aluminum extruded heat sink as above, with included fan bolted to push air through the heat sink. Depending on heat requirements, a second fan may also be provided on
the output of the unit.

Testing Options:
Standard - includes power test and brief burn - in under laboratory conditions. Printed test report gives graph of Gain and Input Return Loss at rated P1dB and Voltage Conditions. Report
shows pass/fail critera. All ampliers include this test.
Extended burn in - 8-hour burn in at P1dB with standard test run at completion. Unit is monitored during test and any discrepancy reported. Standard test data is included.
Extended data collection - Standard data is run and included. Detailed data is taken point by point giving the customer 25 - 70 frequency points, depending on the amplier model. For each
frequency point, data is generated to include gain, input power, input return loss, current, second harmonic, third harmonic, efciency, audio distortion.
Other tests available - Vibration, Temp cycling, Shock. Please inquire.
