RF Amplifiers

Modulated RF Power Amplifiers
RF Wideband Pre-Amplifiers
RF Driver Amplifiers

Wideband RF power amplifiers and RF signal generators are critical components in both radiated and conducted immunity tests. The combined cost of the requisite immunity test equipment is prohibitively expensive for pre-compliance applications.
Tekbox created a low-cost solution comprised of modulated RF power amplifiers driven by spectrum analyzer tracking generators. Our amplifiers include built-in modulators that produce the typical modulation forms defined by the applicable standards, as tracking generators provide a CW output signal: 1 kHz, 80% AM, 1 kHz, 50% duty cycle PM, 217 Hz, 12.5% duty cycle PM.
Our EMCview software controls the frequency and output power of the tracking generator during testing.

Depending on model, our amplifiers currently cover the frequency range from 100 kHz to 1.5 GHz and the available output power covers the range from 150 mW to 25 W.
The modulated amplifiers are suitable for pre-compliance radiated immunity testing in TEM cells and pre-compliance conducted immunity testing with CDNs or bulk current injection probes.
