So you're looking at the SRD-DPA-30, and I've been moving these for about three years now. We usually see buyers who are building out custom jamming rigs for cell bands, or doing RF shielding tests in controlled environments, and honestly the 30W output gives you a solid workhorse without overcomplicating the thermal design. It basically covers 20MHz all the way up to 6000MHz, which means you can hit GSM CH1, 4G, 5G sub-6, Wi-Fi, and even some ISM bands — pretty much anything you'd need for signal blocking in a lab or field trial.
One thing people miss is that 30W is output power at the connector, not power consumption — the unit draws about 85W from a 28-32V DC supply, so plan for that margin. The N Female connector is standerd, but check your cabling because (and we've had this issue) some cheap N plugs don't mate well at the higher frequency end, and you'll lose gain around 5-6GHz. We include a basic heat sink pad, but in my experience, if you're running sustained CW near 30W for more than 10 minutes, you'll want active airflow or a bigger fin array.
Frequency flatness is better than reagent grade on most units, though I've seen about ±1.5dB at 5.8GHz in a couple of samples. The blocking frequency spec for GSM CH1 is tight — it's one of the reasons buyers go with this over a generic wideband amp, because the front-end filtering is decent. Anyway, I'd suggest running a 1-hour soak test before putting it into production; we've had units that drift 0.3dB at -20°C until they stabilize.
What you get in the box is the amplifier module itself, a datasheet with typical curves, and a one-year warranty on defects. We don't include the power supply — that's something to plan for seprately, preferably a linear supply with ripple below 10mV at 30V. Also, this is not suited for continuous high-duty-cycle radar pulses or communication base stations, because the recovery time on the AGC is roughly 50ms, and that's just a fact for this price point. Dimnesions are 117 by 40 by 18mm, and it weighs about 1kg, so it's compact but not pocket-sized.
85W power consumption at full tilt, but idle draw is negligible — you'd barely notice it. The operating humidity range from 30% to 95% is standard for this class, but if you're working in a damp environment, sealing the enclosure with gasket tape is good habit. One detail not on the spec sheet: the PCB uses FR4 with thermal vias rather than ceramic, so prolonged exposure above 50°C ambient will shift the output power margin. We usually have stock, but confirm lead time if you need more than 20 units — that's our typical MOQ for batch pricing.
It's way better than a generic driver stage for jamming, and the 30W range gives you about 15dB margin at 2.4GHz over a 10mW source. Most buyers go with the module for DIY builds because of that it's self-contained, but you'll need a heatsink compound from your shop — we don't bundle that. Anyway, consider a simple fan shroud if your rack stays over 35°C; it's not critical, but it's what experienced builders do.
You need a DC source between 28 and 32 volts that can deliver at least 85W — so a 3A or higher supply is safe. It doesn't have to be a special model, just stable and within that range.
Yes, the 30W is at the N Female output. The ±1dBm tolerance means you'll see between roughly 29W and 31W across the full 20-6000MHz range, so it's pretty consistent.
It meets general industry standards for RF amplifiers, but we don't offer a specific test report per unit. If you need documentation for a particular certification (like CE or FCC), let us know and we can check availability for your order.
MOQ is 1 piece, so you can order just one for your DIY jammer project. We usually have stock for single units, but lead time is around 3-5 business days if not.
Just keep it in a dry place within -20°C to +50°C and 30%-95% humidity — the same range it operates in. No special packaging needed, but avoid direct moisture.
