PIN1: 1dB Attenuation |
PIN2: 2dB Attenuation |
|
PIN3:4dB Attenuation |
|
PIN4: 8dB Attenuation |
|
PIN5:16dB Attenuation |
|
PIN 1~5: (Hang in air or add 5VDC: No attenuation; Grounding: attenuation) |
|
PIN7: V/L, VSWR(reflected RF Power, Max voltage,3.3V; 0.1V/1dBm) |
|
VSWR Alarm TTL High(5V)@reflected power 25~50W –the alarm is not latched signal |
|
PIN10:P/L(Output RF Power; Max voltage,3.3V; 0.1V/1dBm) |
|
PIN11: LE :Enable, High Level: OFF; Low Level: ON |
|
PIN14: T/L temperature Monitor VT(10mV)*Tc(℃)+500(mV)->TC=Case temperature +/- 5℃Over Temp Alarm and shutdown: High(5V)-case temp.85+/-5℃ –Auto Restart Low@case temp.65℃ |

PIN15: GND |
|
Other: NC |
Feature:
l The general Power Amplifier can be used for Jammer, BDA, Repeater, BTS, or Lab equipment.
l Pout is stable over -20~65℃
l Efficiency is more than 30% for 50W
l Over-high VSWR to avoid or reduce the damage from any mismatch
l Over-high temperature protection, Shutdown more than 75℃, auto-restart less than 50℃
l DB15 serial port is standard, DB9 Parallel RS485 is optional(China Mobile Protocol)
Remarks
l PA should operate on an appropriate radiator, or it would shutdown over high-temperature.
l Pout port can't open or short, otherwise PA maybe get burned and damaged.
l Pout port should be connected to a probably Load, Attenuator or antenna (50 ohms, more than 100W handling Power, lower than VSWR 2.0).
l The power range and polarity of power supply must correct, otherwise will damage the PA.
l Pout probably is lower the rated power if input Power is lower than 5dBm; PA probably is damaged if input power is higher than15dBm
