PA1410/PA810 for DLM/DLB Module

This PA1410(or PA810) amplifier is a 10W linear power amplifier, designed for using with Sihid DLM/DLB module.


  • Frequency band: 1425MHz-1455MHz(PA1410), 800MHz-830MHz(PA810)
  • RF in: DLM(or DLB) module RF out(25±2dBm)
  • RF out power: 10W(40dBm)
  • Tx gain: 18dB, when used with DLB/DLM module, set up the maximum RF power of DLB/DLM as 22~24 dBm, then the RF out power will be 40~42dbm.
  • Power in: DC24V~30V, minimum 2.5A@28V power current rating
  • Power consumption: <28W average
  • Dimensions: 65*62*13.5mm, not including the connector out of the metal housing
  • Weight: 98g
  • Impedance: 50 ohm

Working together with DLM(or DLB) Module:


Power in VDD(red) and GND(black) cable. It’s suggested to power with DC28V.
Control Two cables, should be connected with DLM(or DLB) Switch signal pad(SCL and GND). The input high(1.8V to 3.3V) will drive the amplifier and work in Tx mode. The input low will enable the PA module to work in Rx mode.
RF in IPEX connector for connection with main antenna of DLM(or DLB) module.
RF out SMA female connector

Heat dissipation

The back side of the PA module should be assembled to metal directly and tightly to help heat dissipation. For optimal performance it is important to include adequate heat dissipation strategies that incorporate a heat sink or fan into any designs that integrate the PA module.
