• 500MHz Power Head

The DC to 500MHz RF Power Head Kit uses the AD8307 Logarithmic amplifier, and can either be used in conjunction with the Mini-Kits DDS VFO KIT using the optional SWEEP software, or be used with a DC voltmeter for simple RF Power measurements.  An on board PIC micro-controller calibrated with SWEEP software is used to convert the analogue DC volts from the AD8307 to I2C data and clock which is available on the header connector.  For more information on the RF Power Head and SWEEP software see the EME151 RF Power Head Webpage.

The Product image shows a fully constructed EME151-500M 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.

EME151-500M KIT is a basic Kit that includes the PC board, construction notes, and all on board components. No connectors or enclosure are included. Requires complete construction and soldering of small SMD components.

EME151-500M KITB is a fully constructed and tested board with a female SMA39 connector.

EME151-500M PCB Only includes the PC board and Kit construction notes. No on board Components are included.

Hammond 1590A enclosure is ideal to mount the RF Power Head.  Use the SMA39 connector that has a nut and washer for easy mounting into the enclosure.

Please note the supplied PIC micro-controller has a standard calibration pre-programmed.  More accurate calibration is done through a setup menu when using the DDS-VFO Kit using SWEEP software.

Kits and built products Do Not include miscellaneous hardware, or an enclosure. For advanced constructors due to the small SMD components.
