100W GaN Wideband Module 1500-2500MHz

When your RF chain demands instant coverage across 1500 to 2500 MHz without swapping hardware, the AMP15002500‑100W wideband module steps in as a straightforward, no‑compromise solution. Designed around Gallium Nitride on Silicon Carbide (GaN‑on‑SiC) technology and housed in a compact copper sub‑carrier, this unit delivers a solid 100 watts of peak output power with a typical gain of 50 dB – all while keeping efficiency around 30%. Whether you are building test equipment, jamming systems, or broadband communication links, this module handles the heavy lifting with minimal fuss.

What makes this wideband module different?

The first thing you notice is the instantaneous bandwidth – no tuning, no band‑switching relays, just a flat 2000 MHz of usable spectrum from a single RF port. The Class AB GaN design strikes a practical balance between linearity and power consumption, and the patented thermal management keeps the junction cool even during prolonged CW operation. With 50‑ohm input and output impedance, integration into existing 50‑ohm systems is essentially plug‑and‑play. The module also includes built‑in monitoring features: a temperature monitor output (0.75 V at 25°C, scaling 0.01 V/°C), a current monitor pin, and an HPA enable line for remote on/off control.

Environmental and mechanical toughness

This module is built for real‑world conditions. It operates over a case temperature range of –20°C to +85°C and can be stored between –40°C and +105°C. Non‑condensing humidity up to 95% RH is tolerated, making it suitable for outdoor enclosures or lab environments with variable climate. The mechanical envelope is surprisingly compact: 168.5 × 82.8 × 26.5 mm (without connectors) and weighs only 0.75 kg. RF connections use an MCX female input and a rugged N‑type female output – a combination that gives you a small‑footprint input side and a robust, low‑loss output interface. DC power feeds through a feed‑through capacitor with a male supply pin, and the 8‑pin header provides access to enable, RS‑485 (A/B), external TTL lines, and monitoring outputs. Remember that an external heatsink is mandatory – the module dissipates significant heat at full power, so proper thermal management is not optional.

Where does this module shine?

Given its wide, uninterrupted bandwidth and 100‑W capability, we see this module used in:

• Broadband test stations – one amplifier replaces multiple narrowband units for swept measurements.

• Electronic warfare (EW) simulators – fast frequency hopping requires instantaneous response, and this module delivers without retuning.

• Military and aerospace communication – the GaN‑on‑SiC technology offers high ruggedness against load mismatches and overdrive.

• Radar pulse amplification – the Class AB bias supports both CW and pulsed modes with good linearity.

• General‑purpose laboratory amplification – when you need a reliable, predictable gain block that covers S‑band.

The ±3 dB gain flatness across the entire band means you won’t waste time equalising your test setup, and the 2:1 VSWR limit ensures safe operation even with imperfect antenna loads.

Design details that matter

The copper sub‑carrier and patented heat‑spreading architecture allow the GaN die to run cooler than many competing designs. That directly translates to longer MTBF and stable performance over hours of operation. The temperature monitor output (0.75 V at 25°C, with 0.01 V per °C slope) gives you real‑time die temperature feedback – you can implement a software shut‑off or fan control loop without adding extra sensors. Similarly, the current monitor pin lets you detect abnormal consumption, which is a handy diagnostic for preventive maintenance. The RS‑485 interface (pins 4 and 7) offers remote supervision and control, while the PA_EN pin (pin 6) allows you to gate the amplifier with an external TTL signal – useful for pulsed applications or safety interlocks.

Whether you are upgrading an existing test rack or designing a new multi‑band transmitter, the AMP15002500‑100W wideband module offers a proven, off‑the‑shelf answer to the 1.5‑2.5 GHz challenge. Its combination of GaN efficiency, wide instantaneous bandwidth, and comprehensive monitoring makes it a workhorse that engineers can trust.
