<p>The present invention relates to a wideband/high power FM transmitter for telemetering using a monolithic microwave integrated circuit (MMIC) amplifier impedance-matched with a main amplification unit, and configuring an amplifying unit with 4 stage amplifiers. To achieve this, the wideband/high power FM transmitter for telemetering includes: a modulation unit converting an arbitrary signal into a signal of a preset frequency band, outputting a signal; an amplification unit amplifying the signal output from the modulation unit; and a power supply unit supplying power to the amplification unit, wherein the amplification unit includes a band pass filter band-passing the signal output from the modulation unit; a free-amplification unit amplifying the band-passed signal through a 3 stage amplifier; a main amplification unit additionally amplifying the 3 stage amplified signal based on a voltage received from the power supply unit; and a low pass filter low-band-passing the additionally amplified signal.</p> |
