100W Power Amplifier Monitoring Function Description:
| SN | PIN | Function | Description |
| 1 | SWR | VSWR Alarm | If VSWR exceeds4:1,an alarm is generated and PA will off |
| 2 | TEMP | Temperature alarm | Module case temperature exceeds 65°C, generates an alarm and reach 75°C, turn off the amplifier, until the temperature returns to below 55°C, re-open PA.
When generate a alarm, the output TTL level are 3.3v.and when it is working normal, level is 0v |
| 3 | PTT | Enable | PA ON when PTT is Low level or no level (ground) and PA OFF when PTT is High level (+5V), pulled-up with 10kΩ. |
| 4 | GND | Grounding |
Power Amplifier Design
Reflected power caused by a high VSWR condition between a PA and its load does not, in and of itself, cause a transistor’s destruction or damage.
Rather, a PA can be damaged or destroyed in a high VSWR environment simply because it is now looking at a completely different load impedance than it was designed for.
High device power dissipation can then produce elevated heating of the transistor and/or excessively high voltages.
Some of the DC bias voltage would be wasted if the resistance in the chokes were too high. Also, the collector chokes must supply a very high impedance to the RF. If this impedance is not high enough, then some of the valuable RF output power generated by the PA will be wasted.
Use low-ESR electrolytic capacitors at the PA’s power supply, as this type of capacitor can immediately supply the needed current to the amplifier stage, and without pulling down the entire voltage supply during this critical transient turn-on time.
When in saturation, a nonlinear PA’s gain, PAE, and linearity are most affected by the reflections of its own harmonics back into its output port. These reflections are caused by the next stage, which will normally be a band-pass or low-pass filter, as well as an antenna.
Instability in RF amplifiers can take the form of oscillations at almost any frequency, and may even damage or destroy the transistor.
These spurious oscillations will arise at specific or very wide-ranging, frequencies or frequencies, and over a particular bias, drive level, temperature, or output load impedance.
