Overview
The DesTest TS-PA6000L is a compact, high-performance broadband RF power amplifier engineered for precision signal amplification across the 1.5–6.0 GHz frequency band. Designed using monolithic microwave integrated circuit (MMIC) architecture with GaAs pHEMT active devices, it delivers stable, linear gain characteristics under varying load and temperature conditions. Its internal microcontroller manages real-time gate biasing, power-up sequencing, and closed-loop thermal compensation—eliminating external bias supplies and reducing system integration complexity. Unlike legacy amplifiers requiring manual tuning or external attenuators, the TS-PA6000L implements digitally controlled analog gain regulation with 0.25 dB step resolution, enabling repeatable amplitude calibration in automated test systems. The device complies with MIL-STD-704F for transient voltage immunity and meets IEC 61000-4-2/4-3 for electrostatic discharge and radiated immunity—making it suitable for deployment in aerospace ground support equipment, defense electronics validation, and EMI/EMC pre-compliance testing environments.
Key Features
- Compact form factor (102 × 76 × 25 mm) optimized for rack-mounted ATE systems and portable lab setups
- Fully integrated digital control architecture with SCPI command set over USB virtual COM port (no drivers required on Windows/Linux/macOS)
- Onboard telemetry monitoring of junction temperature, supply rail voltage, and output power derating status
- Gold-plated 18 GHz microwave-grade SMA connectors ensuring consistent VSWR <1.8:1 across full bandwidth
- Gain flatness ≤ ±0.8 dB over 1.5–6.0 GHz at 25°C; maintained within ±1.2 dB from –20°C to +65°C ambient
- No external bias tees or DC blocking capacitors required—input/output ports are DC-coupled and internally matched
Sample Compatibility & Compliance
The TS-PA6000L supports standard 50 Ω RF signal sources including vector signal generators (VSGs), arbitrary waveform generators (AWGs), and spectrum analyzers with tracking generator outputs. It is compatible with common modulation formats (QPSK, 16-QAM, OFDM) up to 100 MHz instantaneous bandwidth without measurable AM-PM distortion (<2° phase shift per dB gain change). Regulatory compliance includes FCC Part 15 Subpart B (unintentional radiator), CE RED Directive 2014/53/EU, and RoHS 3 (2015/863/EU). For GxP environments, firmware logging supports audit-ready timestamped gain/temperature/voltage records traceable to NIST-traceable calibration standards.
Software & Data Management
Control and configuration are performed via industry-standard SCPI commands transmitted over a USB CDC ACM interface (VID: 0x1209, PID: 0x2B1F). DesTest provides open-source Python SDK (PyPI: destest-pa) with built-in support for NI TestStand, Keysight PathWave, and Python-based PyVISA automation frameworks. All gain settings, thermal thresholds, and fault logs are stored in non-volatile memory with write-cycle endurance >100,000 cycles. Firmware updates are delivered as signed binary packages validated using SHA-256 and ECDSA signatures—ensuring integrity per IEC 62443-3-3 requirements for industrial control systems.
Applications

- Over-the-air (OTA) antenna characterization in anechoic chambers where low-profile amplification minimizes chamber reflections
- Wireless link budget validation for satellite communication terminals operating in L/S/C bands
- EMI susceptibility testing per IEC 61000-4-3, serving as a calibrated RF stimulus source up to 6 GHz
- Academic research in millimeter-wave propagation modeling, where gain repeatability enables multi-node coherence analysis
- Calibration reference amplifier in metrology labs accredited to ISO/IEC 17025:2017 for RF power transfer standards
FAQ
Does the TS-PA6000L support remote triggering via TTL or Ethernet?
No—only USB virtual COM port control is implemented. For Ethernet integration, use a USB-to-Ethernet server compliant with CDC ACM class enumeration.
What is the maximum input power before damage occurs?
Absolute maximum input is +20 dBm continuous wave; operation above +17 dBm requires derating above 55°C ambient per datasheet Section 4.2.
Is factory calibration certificate included with shipment?
Yes—a NIST-traceable calibration report covering gain, output power, and return loss at 10 discrete frequencies across the band is provided with each unit.
Can the amplifier be operated in pulsed mode?
Yes—pulse width ≥10 µs and duty cycle ≤20% are supported without thermal throttling; rise/fall times are <15 ns (10–90%).
Does firmware support user-defined gain profiles?
Yes—up to 8 programmable gain-vs-frequency lookup tables can be loaded and recalled via SCPI command :GAIN:PROFILE:LOAD.
