Amplier Picture

This ultra broadband class A amplier operates from below 1 MHz to over 1 GHz. Using all gold

metallized LDMOS transistors and a stable design, this compact, high performance laboratory amplier

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.

4886 LA2-1-1025-33 Integration and Operating Instructions Attach amplifier to heatsink using thin layer of thermal compound. The amplifier 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 airflow is used. Attach RF Input and RF Output using SMA Female connectors and tighten.
