Modulated RF Power Amplifiers
Tekbox Modulated RF Power Amplifiers are a comprehensive family of cost-effective, high-performance wideband amplifiers engineered specifically for pre-compliance radiated and conducted immunity testing. Designed to work seamlessly with the tracking generator outputs of standard spectrum analyzers, these amplifiers eliminate the need for costly dedicated RF signal generators — making professional-grade immunity testing accessible for in-house pre-compliance use.
The product family spans an extensive frequency range from 100 kHz to 3 GHz and delivers output power from 150 mW up to 100 W, covering virtually all immunity test scenarios defined by international standards. Each amplifier in the series integrates a built-in modulator capable of generating the modulation forms required by the relevant EMC standards: 1 kHz 80% AM, 1 kHz 50% duty cycle pulse modulation (PM), and 217 Hz 12.5% duty cycle PM to simulate GSM/TDMA mobile phone noise — all driven directly from the CW output of a spectrum analyzer tracking generator.
Tekbox modulated amplifiers are suitable for a wide range of pre-compliance test applications. For radiated immunity, they are optimized to drive Tekbox TEM cells (TBTC0 through TBTC3) to generate electric fields ranging from tens of volts per meter up to over 700 V/m (CW), enabling systematic testing against IEC/EN standards. For conducted immunity, they are designed to drive Coupling/Decoupling Networks (CDNs) according to EN 61000-4-6, and Bulk Current Injection (BCI) probes according to ISO 11452-4 — covering test levels from Level 1 through Level IV. The portfolio includes compact USB-powered driver amplifiers (TBMDA1, TBMDA2, TBMDA7) for lightweight bench use and higher-power mains-powered models (TBMDA3B, TBMDA4B, TBMDA5T, TBMDA-CDN25, TBMDA-BCI25, TBMDA-BCI100) for demanding test environments. The TBLPA1 rounds out the series as a general-purpose linear wideband amplifier without a built-in modulator.
All amplifiers are fully compatible with Tekbox EMCview software, which controls the tracking generator's frequency sweep and output power during testing, enabling automated, repeatable pre-compliance immunity test routines. With their wide selection of models and competitive pricing, Tekbox Modulated RF Power Amplifiers provide an unmatched solution for engineers who need reliable, standards-compliant immunity testing capabilities without the investment of a full EMC test laboratory setup.
Built-In Modulation
All Tekbox modulated amplifiers include an integrated AM/PM modulator generating the exact waveforms required by EMC immunity standards — 1 kHz 80% AM, 1 kHz 50% PM, and 217 Hz 12.5% PM for GSM simulation — so no external signal generator is needed.
Wide Frequency & Power Range
The product family covers frequencies from 100 kHz up to 3 GHz and output power from 150 mW to 100 W, providing a scalable solution for TEM cell radiated testing and conducted immunity testing with CDNs and BCI probes at all standard test levels.
Pre-Compliance Cost Savings
By using a standard spectrum analyzer's tracking generator as the signal source, Tekbox amplifiers dramatically reduce the cost of radiated and conducted immunity test setups — making pre-compliance testing practical for development labs, design engineers, and EMS companies.
Standards-Compliant Testing
The amplifier range supports pre-compliance testing per IEC/EN 61000-4-6 (conducted, CDN), ISO 11452-4 (BCI), and radiated immunity testing in TEM cells — enabling systematic, repeatable results that closely correlate with full accredited laboratory test outcomes.
Tekbox Modulated RF Power Amplifiers offer a smart, affordable approach to pre-compliance immunity testing. With built-in modulators, wide frequency coverage from 100 kHz to 3 GHz, and output power up to 100 W, the complete product family enables both radiated and conducted immunity tests using standard spectrum analyzer tracking generators — no dedicated RF signal generator required.
From compact USB-powered driver amplifiers to high-power mains units for BCI probe testing, the Tekbox TBMDA series delivers the power, bandwidth, and modulation needed for pre-compliance immunity testing per IEC/EN 61000-4-6 and ISO 11452-4. Fully compatible with Tekbox EMCview software, these amplifiers make professional-grade immunity testing accessible and cost-effective for any development or production test environment.
