By Ampleon 22
The BLF645 from Ampleon was developed as a multi-purpose device, with broadcast and ISM applications in mind. The device is based on Ampleon’s 32 V LDMOS technology, is unmatched and boasts > 100 W P1dB output power at 18 dB gain and 56% drain efficiency in the frequency range from 1 to 1400 MHz. The package is of the push-pull type to optimize for broadband operation.
For power amplifiers in the frequency range of 10 MHz to 3.8 GHZ, RF Laterally diffused MOS (LDMOS) transistors are the established choice of technology because of their excellent power capabilities, gain, efficiency, linearity, reliability and low cost. This technology also delivers for broadband applications in broadcast and ISM (industrial, scientific and medical), where additional requirements like bandwidth, ruggedness, and thermal resistance are important.
