30W LDMOS Drone Jamming Module – 758-788MHz Blocker

Lightweight LDMOS Power for the 758-788MHz Band

Not every jamming mission requires a 100W brute. Sometimes you need a nimble, power‑efficient module that still packs enough punch to disrupt drone control links in the 758–788MHz range – a band used by various military and commercial UAV command systems. This 30W drone jamming module fills that gap perfectly. Built around mature LDMOS technology, it delivers a solid 30W of clean swept noise while keeping size and weight to an absolute minimum. At just 115.5×46.5×21mm and 210 grams, this module is ideal for handheld jammers, small UAV‑mounted countermeasures, or discreet portable kits where every gram counts.

Core Specifications and Built‑In Sweep Generator

The amplifier operates from a 24–29V DC supply, drawing only 3.2A at full output – a very modest current for 30W of RF power. The typical efficiency is ≥40%, which translates to less heat generation and longer battery life in mobile applications. Like its bigger siblings, this module comes with an integrated high‑speed sweep source, so you don’t need an external signal generator. Just apply power, enable the module via the logic control (+5V or floating for ON, ground for OFF), and it starts sweeping across the entire 758‑788MHz band. The sweep rate is factory‑set, but we can customise it to match specific receiver characteristics. The RF interface uses a standard SMA‑female connector, and the input/output impedance is 50Ω, ensuring compatibility with common antennas and cabling.

Thermal Management and Rugged Construction

Even with lower power, heat dissipation matters. The LDMOS die is mounted on a copper baseplate that efficiently transfers heat away from the active junction. We recommend attaching the module to a metal chassis or heatsink with thermal grease – a simple measure that keeps the unit well within its -20°C to +65°C operating range. The output VSWR is specified at ≤2.0, which provides a safe working margin for most field antennas. Although there is no explicit VSWR protection circuit, the LDMOS transistor is inherently more tolerant to mismatch than many GaN parts, giving you extra resilience in dynamic environments. The compact aluminium housing adds mechanical strength without adding bulk.

Simple Integration and Versatile Control

The logic‑level enable pin makes this 30W drone jamming module easy to control from a microcontroller, a manual toggle switch, or a remote relay. Ground the pin to disable the amplifier – useful for standby modes or pulsed jamming sequences. The built‑in sweep source is always active when the module is enabled, producing a continuous swept‑noise signal that covers the full 30MHz bandwidth. For users who prefer external modulation, we can bypass the internal source and route an external input through the SMA port – just let us know when ordering. The 30W drone jamming module’s small footprint means it can fit into tight enclosures, such as drone gimbals or backpack radio systems, without compromising performance.

Field‑Proven Reliability for Short‑Range Denial

This 30W drone jamming module is particularly effective against low‑altitude drones operating in the 758‑788MHz segment. With proper antenna gain, it can create a reliable denial zone of several hundred meters, depending on environment and UAV receiver sensitivity. Users appreciate the combination of lightweight construction and consistent output – the amplifier maintains its rated power over temperature and supply fluctuations, thanks to internal bias stabilisation. Whether you are protecting a convoy, securing a perimeter, or testing counter‑UAS tactics, this module offers a cost‑effective, low‑risk entry into the world of RF jamming.

Customisation Options and Ordering Notes

We understand that every counter‑drone scenario is different. That is why we offer sweep speed adjustments, external input modifications, and even customised dimensions for unique form factors. The standard version ships with the internal sweep source, but we can replace it with a VCO or DDS front‑end upon request. For volume orders, we can also adjust the enable voltage logic or add status indicators.
