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 & 1.3GHz. The amplifier is also suitable as a driver amplifier for complex RF waveforms, and produces up to +21dBm output on 400MHz. The Mini-Circuits PGA-103 MMIC uses E-PHEMT technology, and has on chip active bias allowing it to operate directly from supply voltages between +3 and +5vdc. The PGA-103 is specified to 4GHz, but the gain is very non linear & is 10dB lower at 1.3GHz compared to 100MHz.
The Kit includes PC board & all on board components, requires connectors, & miscellaneous hardware to complete.
Built Versions of this Kit are also available, refer to the Options TAB for detailed information.
The PGA-103 KIT is for +5vdc operation only, and would require a +5v regulator to operate on higher voltages. Only the fully constructed amplifiers are fitted with a +5v regulator for operation from +7 to 15vdc.
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.
