ISM band repeaters operating in the 2.4 GHz range need that final push to overcome cable losses or penetrate concrete walls, and this is what a 50-watt module gives you. We set the operating voltage at 28V nominally but it'll still hold gain flat across 24 to 30V, which matters more than people think when your DC rail sags under load. The LED indicator is small but useful—basically tells you bias is alive without having to break out a scope for a quick check.
Gain sits at 47dB flat to within ±1dB, and we measure that across temperture sweeps form -20°C to +55°C not just at 25°C in the lab. Output power hits ≥47dBm into an SMA-female port, so 50 watts continuous and it can handle a slightly mismatched load without folding back. Most buyers go with the 10MHz adjustable bandwidth option, but you can tweak the center frequency if your channel plan is tight.
You'll need to supply clean 28V at up to 4.2A—anything less than a regulated bench supply and you'll see the power stability wander outside the ±1dB spec. 0.23kg with four 3.2mm mounting holes, so a few M3 screws and it's fixed onto your chassis or heatsink. Actually, we usually have these stocked but confirm lead time because ISO batch—every COA is run through HPLC but we don't always preprint them.
Ripple in band is ≤3dB worst-case, which is pretty much for a module at this power level; better than discrete-componnet builds we've seen. 117mm by 58mm footprint so it doesn't crowd your enclosure, and we leave a little thermal margin on the board so it doesn't cook at 65°C ambient. Not great for anything requiring fine gain steps or variable attenuation—this is a fixed-gain brick, not a VGA.
Weight (230g or so) means it doesn't stress mounting brackets, and the SMA connectors are 50-ohm 28V operation—some cheaper modules use lower-grade connectors that arc at this voltage. We've had customers integrate it into drone-based repeaters and fixed indoor DAS systems alike. Anyway, the current draw ≤4.2A holds steady unless you drive the input above -5dBm, which you shouldn't do anyway.
The module is designed to deliver ≥47dBm (50W) output with a gain of 47±1dB, so you’d typically feed it around 0dBm (1mW) input. Driving it harder risks clipping or damage, so keep the input within that range.
Yes, we can share the ISO certificate and a typical test report for the module showing gain, power, and ripple across the 2400-2485 MHz band. Just let us know when you place an order.
MOQ is 10 pieces for stock items. Lead time is usually 7-10 working days for orders up to 100 units, but we can adjust if you need a larger batch.
It ships as a bare module with the 4 mounting holes for Ø3.2mm screws, so you’ll need to attach your own heat sink. The 4.2A current draw at 28V generates noticeable heat, so proper thermal management is required for continuous operation.
The adjustable bandwidth means you can tune the center frequency within the 2400-2485 MHz range, and the ±10MHz refers to the passband around that center. So if you set it to 2440 MHz, you get a 20 MHz wide band from 2430 to 2450 MHz.
