The MGA-31189 amplifier is a high gain 0.25W driver amplifier for use between 50 and 2000MHz, and is ideal for complex RF waveforms, or as a low noise high dynamic range gain block in a receiver. Please refer to the MGA-31189 Data Sheet for further information. A 78M05 regulator is mounted under the board for +7 to 15vdc operation.  This amplifier is ideal as a driver for the BATC DTX-1 DATV Transmitter, for driving a RA18H1213G module to a very linear 5 Watts output.

The Product image shows a fully constructed MGA31189 KITB 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.

MGA31189 KIT is a Basic Kit that includes the PC board, Instructions, and all on board components. Requires complete construction, and soldering of SMD components.

MGA31189 KITB Is a fully constructed and tested PC board Kit including SMA female connectors For 50MHz to 2GHz. No enclosure is included.

MGA31189 B-ENC Is a fully constructed amplifier in a Hammond 1550Q enclosure with female SMA, and 2.1mm DC socket. The 2.1mm DC Lead is Optional

MGA31189 PCB Only includes the PC board and Kit construction notes.

MGA Option2 Select where you want the MGA mounted on the board.  For Receive applications the MGA 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 MGA 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.
