30W Anti-Drone Jamming Module – Compact 600–700MHz LDMOS

Not every counter‑UAS mission requires a heavy brick of RF power. Sometimes you need a nimble, low‑profile jammer that still gets the job done. The 30W Anti‑Drone Jamming Module fits that brief perfectly. Built around reliable LDMOS technology, it delivers a clean 30W across 600–700MHz – a band increasingly used by larger drones for command and video downlinks. At just 0.21kg and 115.5mm long, this module slips into portable kits, handheld units, or small UAV payloads without weighing you down.

Why 600–700MHz for Drone Countermeasures?

The lower UHF band (600–700MHz) offers better propagation through foliage and urban clutter compared to higher frequencies. Many mid‑size and tactical drones use this range for robust control links. The 30W Anti‑Drone Jamming Module concentrates its interference right here, effectively breaking the pilot‑drone connection even in non‑line‑of‑sight conditions. Its internal swept oscillator ensures that frequency‑hopping signals cannot hide for long.

LDMOS – The Workhorse for This Power Class

Instead of GaN, this module uses LDMOS (Laterally Diffused Metal‑Oxide‑Semiconductor) – a mature, cost‑effective technology that excels at 30W levels. LDMOS offers excellent linearity and ruggedness, making it a preferred choice for analog jamming applications where consistent output matters more than extreme efficiency. With ≥40% efficiency, the 30W Anti‑Drone Jamming Module runs cool enough for enclosed spaces, provided you give it basic airflow.

Mechanical Footprint That Fits Everywhere

• Dimensions: 115.5×46.5×21 mm – smaller than many smartphones.

• Weight: 0.21kg – barely noticeable on a gimbal or vest.

• Base material: Aluminium‑core PCB for effective heat spreading.

This slim profile allows integrators to place the module inside tight radio housings or even dual‑stack two units for dual‑band coverage.

Power and Control – Straightforward as It Gets

Operating voltage ranges from 24V to 29V DC, with a maximum current draw of only 3.2A at full tilt. That means you can run it from standard Li‑ion battery packs used in field radios. The on/off logic remains simple: +5V or floating = on, ground = off. The SMA female output connects directly to your chosen antenna – whip, panel, or log‑periodic – without adaptor gymnastics.

Thermal Behaviour

At 30W continuous output, the module dissipates around 45W of heat. While the -20°C to +65°C operating range is generous, we recommend attaching a small heat sink or using the module’s metal baseplate as a mounting surface to a larger chassis. For intermittent duty (e.g., 50% duty cycle), passive cooling often suffices.

Protection and Reliability Without Extra Complexity

The 30W Anti‑Drone Jamming Module includes built‑in VSWR monitoring that folds back output when the antenna mismatch exceeds 2.0:1. Unlike absorptive types used in higher‑power cousins, this LDMOS design uses a reflective limiter – simpler and sufficient for this power tier, with a red LED to alert you. It is not a full‑featured protection circus, but it prevents immediate damage from accidental open/short conditions during field swaps.

Where This 30W Anti-Drone Jamming Module Shines

• Backpack‑mounted drone interdiction systems.

• Vehicle‑roof arrays where weight and height matter.

• Fixed‑site perimeter protection with distributed low‑power nodes.

• Educational labs demonstrating jamming principles safely.

Final Take

The 30W Anti‑Drone Jamming Module offers a sweet spot between output power, physical size, and cost. It does not try to be the loudest gun on the block – instead, it gives you a dependable, lightweight tool for targeted disruption in the 600‑700MHz band. Whether you are a system integrator needing a drop‑in RF block or a field operator wanting a spare jammer for your kit, this LDMOS module delivers honest performance without unnecessary overhead.
