FM Linear Power Amplifiers

The SCA Series of broadband LDMOS based amplifiers offer high performance and high reliability in a compact form factor. Based on custom manufactured bonded fin, oversized heatsink, this design is capable of dissipating 25% more heat than the design requires. This overhead ensures low device temperatures for increased reliability. Using advanced thermal modeling software, RF Amplifiers and other heat generating components are placed carefully on both sides of the heatsink to minimize thermal density.

Using all gold metallized LDMOS transistors, and highly efficient broadband matched amplifiers, this system offers and excellent balance of linearity and efficiency. The PAB series controller monitors all critical amplifier functions, and will protect the amplifier against external faults such as excessive VSWR, overtemperature, AC line faults. In the event of a internal fault, including damaged amplifier, damaged fan or block airflow, damaged power supply, the controller reduces output power to keep amplifier operational.

Front panel and remote control are standard, as well as a number of optional communications protocols including parallel, TTL, Ethernet, RS-485, etc. Additional options include mechanical switch networks, filters, and fast PIN diode T/R switches.
