The PHA-1 amplifier is a simple wideband design which is suitable as a driver amplifier for complex RF waveforms, or as a low noise high dynamic range gain block in a receiver. A PHA-1 MMIC, ( Monolithic Microwave Integrated Circuit ) is used, and has a high OpIP3, and produces up to +22dBm output from 70MHz to 3GHz. Please refer to the PHA-1+ Data Sheet for further information. A 78M05 regulator is mounted under the board for +7 to 15vdc operation.

The Product image shows a fully constructed PHA-1 KITB1 product. Please refer to the Options Tab for the descriptions of the various products available.

Please Note: There is a minimum 2 working day delay to construct built products before they are shipped.

PHA-1 KIT is a Basic Kit that includes the PC board, Instructions, and all on board components. Requires complete construction, and soldering of SMD components.

PHA-1 KITB1 Is a fully constructed and tested PC board Kit including SMA female connectors For 70MHz to 2GHz. No enclosure is included.

PHA-1 KITB2 Is a fully constructed and tested PC board Kit including SMA female connectors For 300MHz to 3GHz. No enclosure is included.

PHA-1 B1-ENC Is a fully constructed 70MHz to 2GHz in a diecast enclosure with female SMA, and 2.1mm DC socket. The 2.1mm DC cable is Optional

PHA-1 B2-ENC Is a fully constructed 300MHz to 3GHz in a diecast enclosure with female SMA, and 2.1mm DC socket. The 2.1mm DC cable is Optional

PHA-1 PCB Only includes the PC board and Kit construction notes.

PHA Option2 Select where you want the PHA-1 mounted on the board. For Receive applications the PHA-1 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 PHA-1 is mounted close to the output connector allowing for an optional input attenuator to be fitted to the board.

Kits Do Not include connectors, miscellaneous hardware, or enclosure. For experienced constructors with some SMD construction experience.
