5600‑5800MHz TDD 20W High‑Performance Linear Power Amplifier
This is a 5600‑5800MHz TDD 20W high‑performance linear power amplifier designed for 5.8GHz wireless communication systems, supporting uplink/downlink dual‑link and TX_EN/RX_EN transceiver switching control. Powered by 32V DC with operating current ≤5A, it provides downlink max output power 43±0.5dBm, gain 48±1.5dB; uplink gain 25±1.0dB, noise figure ≤3dB, in‑band spurious ≤‑36dBm, with excellent EVM and ACLR linearity indicators. Built‑in 0‑16dB numerical control attenuation, over‑temperature/over‑power/VSWR protection, supports RS485 real‑time monitoring and SWIM firmware upgrade. Equipped with SMA‑K/MCX‑K RF connectors, dimensions 165×160×33mm, operating temperature ‑10℃~+55℃, suitable for 5.8GHz TDD private network, base station RF amplification and wireless relay transmission applications.

Downlink Attenuation Value ATT |
Numerical control attenuation, with a gain attenuation range of 0–16 dB and a step of 1 dB; |
Attenuation accuracy:1-20dB≤1.0； |
||||
|
PA Over-Temperature Shutdown Threshold |
The over-high temperature shutdown threshold of the power amplifier is configurable; the power amplifier will shut down automatically when its temperature exceeds this threshold. |
Generally setting 90℃ |
||||
|
Power Amplifier Over-power Shutdown |
The actual power value is 1dB higher than the downlink ALC start-up threshold, which will shut it down. |
|||||
|
Amplifier Fault Alarm |
When the enable switch is set to ON, the query module will generate a fault alarm. |

||||
Query Parameters |
Amplifier Switch Status |
If the amplifier is set to "off", the query should show the amplifier as off; otherwise, it should show the amplifier as on. |
||||
|
Downlink Output Power Level Value |
Detecting the output power value of the power amplifier, detection range（Pomax+2，Pomax-20） |
Detection accuracy: Pout±1dB |
||||
|
Downlink VSWR Value |
When connected to a mismatched load with a VSWR of 1.5 or 2.0, the queried value is ±0.2. |
The VSWR value is readable in real time |
||||
|
Temperature Query |
Detection module internal temperature, detection range: -40℃～+100℃ |
Detection error: ±3℃ |

ALC Value Query |
The displayed value is equal to the actual set ALC value. |

|
ATT Value Query |
The displayed value is equal to the actual ATT value set. |
|||||
Alarm Parameters |
Over-Power Alarm |
An alarm will alarm when the maximum output power exceeds Pomax +1dBm, and will shut down when Pomax +2dBm. |
||||
|
Power Amplifier Over-Temperature Alarm |
When the internal temperature of the module exceeds the "amplifier over-temperature shutdown threshold", an over-temperature alarm will be displayed, and the amplifier will be shut down. The module can only resume operation when the temperature returns to below (amplifier over-temperature shutdown threshold -20℃). |
|||||
|
Amplifier Fault Alarm |
When the power amplifier tube is damaged, a power amplifier fault alarm will be displayed. |
This monitored quantity is reserved in the program, with configurable alarm enable/disable. |
