20W Class A Linear RF amplifier 2.4GHz for ES'Hail2
Frequency is 50MHz / division. Input drive for this example was 7.0dBm. This bias is used for the gate voltage circuit on the power control FET.You must put a 47 ohm resistor in series with the output of this converter then connect the other end to pin 14. This protects the DC converter from inrush current into the 4.7uF tantalum on the amp. There is a logic level enable pin which requires grounding to enable power to this amplifier and can be used for a PTT/KEY control. The connector also has a direct temperature output pin with the function 10.0mV/degree F which measures the board temperature close to the 30W RF output GaAs FET (NEC S2527-30). Note that the output of this amplifier is protected by an internal 125W isolator! Pins 5,6,7,8,10 are all ground. Pins 12,13 are N. Pin 11 is Logic level Low enable, normally floats high. This turns on the +12v to the internal transistors. Pin 9 indicates temperature = 10mV/degree F. This board comes mounted on a 1/4 inch thick aluminum heat spreader which has 6 mounting holes for mounting to a heat-sink. 086 hard-line sections as well as the mating bias connector as shown. You will find it very easy to remove one of the MCX connectors from one end of these and replace it with a SMA. Board dimensions are 6.5 x 4 inches. Fixed Priority S&H quoted prices are for 50 USA states.
