| Power Gain | 50 dB | |
| Gain Flatness | ±1 dB | |
| Input / Output Impedance | 50 Ω | |
| Harmonics @ 100 W | -50 dBc | |
| Spurious Signals | -60 dBc | |
| Operating Voltage | 28 VDC | |
| Power-Added Efficiency | 22–30% |
GaN Technology for High Power Density
A key technology behind the module is the use of Gallium Nitride (GaN) combined with chip-and-wire manufacturing technology.
This architecture is designed to provide strong power performance while maintaining a compact form factor and favorable power-to-volume ratio. The manufacturer specifies the module as a small-size, lightweight and instantaneous ultra-broadband amplifier with 50-ohm input and output matching.
For system designers, the compact architecture can simplify integration into RF equipment where available space and thermal management are important design considerations.
Built-In Protection and Monitoring Functions
Reliability is an important consideration for high-power RF amplifiers. The ZD-SSPA-8/12G-100W incorporates control and protection circuits for monitoring operating conditions.
The module includes protection against:
- Over-temperature
- Over-current
- Excessive operating conditions
The thermal protection is specified at 85°C ±5°C, with automatic shutdown when the module temperature exceeds the specified threshold. After the temperature falls below 65°C, the module can automatically restart.
The current protection function provides an alarm output, and the module automatically shuts down when the specified over-current condition persists.
These built-in functions help system developers monitor amplifier status and integrate protection mechanisms into larger RF systems.
Compact Mechanical Design
Despite its high-power output capability, the amplifier module has a compact mechanical configuration.
The specified maximum dimensions are:
160 × 120 × 25 mm
with a maximum weight of 2.0 kg.
The module uses an SMA-K female connector for RF input, an N-K female connector for RF output, and a hybrid 7W2 mixed-contact D-Sub connector for the DC interface.
This compact mechanical structure allows the amplifier to be considered for RF equipment where installation space and system integration are key requirements.
Designed for Professional RF Applications
According to the product specification, the ZD-SSPA-8/12G-100W is suitable for applications including:
- RF test and measurement
- EMC applications
- High-power RF systems
- Broadband RF amplification
- Electronic systems requiring wideband high-power amplification
The module is specifically described as suitable for jamming, EMC, and test and measurement applications.
For system integrators and RF equipment manufacturers, the combination of wideband frequency coverage, high saturated output power, integrated protection, and compact mechanical dimensions provides a flexible platform for specialized RF system development.
Environmental and Reliability Considerations
The SSPA module is designed for operation between -20°C and +50°C, with a non-operating/storage temperature range of -25°C to +65°C.
The environmental specification also lists 95% relative humidity, non-condensing.
The module's protection and monitoring functions are designed to help maintain safe operation under demanding conditions and provide system-level status information through dedicated control interfaces.
A Flexible Platform for RF System Integration
Modern RF systems increasingly require amplifiers that combine high power with broadband operation and compact mechanical integration.
The ZD-SSPA-8/12G-100W addresses these requirements through a combination of GaN technology, wide frequency coverage, high power gain, integrated protection, and compact packaging.
With an operating range extending from 7.8 GHz to 12.3 GHz and saturated output power specified from 100 W to 160 W, the module provides RF system designers with a broad operating platform for applications across the X/Ku-band region.
