The GALI-74 driver amplifier is a straightforward design with a wide-band gain of better than +21dB, specifically designed to operate within the frequency range of 500kHz to 2GHz. Its primary application lies in serving as a transmitter driver, delivering an output power exceeding +18dBm at 1dB compression across the entire HF to 2GHz range.
Tested with a NanoVNA configured with a bandwidth ranging from 100MHz to 800MHz, it displayed a gain of 22dB at the frequency of interest, 436MHz. This gain result across the spectrum from 100MHz to 800MHz generally aligns with the specifications outlined by MiniKits SA for the kit.
