30W Class A Linear RF amplifier 2.3-2.45 GHz 2304 ATV +
30W Class A Linear RF amplifier 2.3-2.45 GHz 2304 ATV +. This is for one very linear Class A RF amplifier which I have removed from a new Spectrian high power Amp where it was used for driver for the main PA boards.
This amplifier has been selected, setup and tested for an output power of 30W from 2.3GHz to 2.35GHz with a linear gain of 35dB. Input power for 30W output is typically 10mW or less!I have attached a plot of power vs frequency. The upper left reference tick marks the 100W (50dBm) point with 5dBm / vertical division. 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. 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. When using 30W Spectrian amps at 2.4GHz do not input more than 10dBm. Do not expect or try to get more than 20-25W output.
Do not allow the supply current to exceed 10A. Failing do follow these requirements will result in a blown final FET. Fixed Priority S&H quoted prices are for 50 USA states.
