The PA-TR3-400M and PA-TR3-800M are power amplifier modules operating in the UHF frequency band and designed to be connected to Circuit Design’s RF modules for applications requiring higher power transmission. The Amplifier/Through Line selectable circuit allows operation in half-duplex applications. The module operates with only 3 V power supply and has a gain up to 17 dB which is adjustable with the adjustment volume.
The small-thin package (5 mm high) enables installation in compact equipment.
It is prohibited to use radio devices with output power exceeding the limits specified by radio laws and regulations in each country. Before using this power amplifier, it is recommended to contact the regulatory authority in each country to verify conformity with the legal requirements for the intended frequency range.
