PGA-103 Low Noise VHF/UHF Amplifier
The PGA-103 amplifier is ideal as a Very Low Noise high dynamic range amplifier for use between 100MHz and 1.3GHz. The amplifier is also suitable as a driver amplifier for complex RF waveforms, and produces up to +21dBm output on 400MHz. The PGA-103 is specified to 4GHz, but the gain is very non linear and is 10dB lower at 1.3GHz compared to 100MHz. This Kit has been updated and now has an onboard 78M05 regulator to allow a power supply voltage between +7 to +15vdc to be used.
The Kit includes PC board and all on board components, requires connectors, and miscellaneous hardware to complete.
Fully Built amplifiers are available as a constructed PC board with SMA connectors, and also fully constructed in a Hammond diecast enclosure. Refer to the Options TAB for detailed information.
Please refer to the PGA-103+ Data Sheet for further information

PGA-103 Option2 Select where you want the PGA-103 mounted on the board. For Receive applications the PGA-103 is mounted close to the input connector for a lower noise performance, allowing for an optional output attenuator to be fitted to the board. For Transmit driver applications the PGA-103 is mounted close to the output connector allowing for an optional input attenuator to be fitted to the board. The SMA39 connector will be mounted on the end of the board closest to the PGA-103.
