1. General Description
The PA516 Series are full-featured, high performance RF Power Amplifiers for the AM frequency band.
Two models are available. The PA516A covers operation across 531KHz-1250KHz, and the PA516B covers
531KHz-1750KHz. The PA516A may be used where IM products of lower frequencies in the range need to be
suppressed above 1250KHz, or the PA516B may be used where such suppression is unnecessary, or where full
band operation is required from a single unit.
These units offer high linearity amplifier performance that is suited for multi-carrier operation, and are packaged in a
compact 19inch rack mount, 2RU enclosure.
Figure 1 – PA516 Block Diagram
Various operating parameters are monitored and out-of-tolerance status alarm outputs are provided for use if desired.
Alarm conditions provided include;
Minor Alarms: Excessive VSWR.
Cooling fan speed out of limits.
Internal voltage rail out of limits.
Major Alarms: Output power level more than 6 dB different from configured reference level.
Internal temperature is above 85˚C.
PA has been shut down due to excessive reverse power.
Front Panel LED indicators display the units’ power, enabled state, VSWR and alarm status. These PA516 series
units are available for operation from 240VAC +/-10% power systems.
Supporting documents including this User Manual, a Product Brief, an Application Note, and Service Bulletins are
available from RFI.

4. Unpacking
The PA516 unit is packed in heavy-duty cardboard packaging.
Packed with the units will be the Factory Test Sheet (FTS). The User’s Manual is available for download from the
RFI website.
It is recommended to retain the Factory Test Sheet for future reference.
Although the packaging has been designed to provide suitable product protection during shipping, it is important to
report any visible damage to the carrier immediately.
It is the customers’ responsibility in the event of product damage, to lodge a damage claim with the carrier within a
short period of time after receipt of the package. The time window for lodging the claim should be ascertained from
the specific carrier as this may vary between carriers (typically 1 to 5 days).
Please dispose of all packaging material responsibly.
