- Includes a DC/DC with adjustable output voltage
- Monitoring circuit offers the capability of auto-protection
- Can be easily integrated in a FM transmitter or exciter
Summary
RFA6104A power amplifier module is primarily designed for FM transmitters and exciters. The genuine design of the two-stage power amplification guarantees a power gain of 45dB so that the input of 0dBm is allowed for the 30 Watts typical output. A low-pass filter is included in the module to suppress the harmonics to lower than -60dBc. RFA6104A module also has built-in monitoring functions of the temperature, forward/reflected power, and DC current and voltage conditions.
