RF preamplifier

The models TBWA2 / 20dB and TBWA2 / 40dB are low-distortion preamps, tailored for use with near-field probes. These amplifiers produce significantly less non-linear distortion than the built-in pre-amplifier of the spectrum analyzer. They are connected between near-field probe and spectrum analyzer.

The new TBHDR1 is also a low-distortion preamps, but primarily for use with an artificial network (LISN) was developed. Specifically, while there is a risk of very high peaks in measurements with the AC LISN, there are standards with the DC-LISN (z. B. CISPR 25 Class 5, in the upper frequency range) at which the limit values are close to the noise floor of common spectrum analyzers. In this case you have to use a preamplifier. The lower limit frequency of the TBHDR1 is less than 30 kHz, while the lower limit frequency of TBWA2 amplifier is about 2 MHz.

RF driver amplifier

TBDA1 / 14dB and TBDA1 / 28dB and the modular TBMDA1 are called. Driver amplifier to drive power amplifiers. The TBMDA1 is designed to be controlled by the tracking generator of the spectrum analyzer. It offers the possibility 1 kHz AM or PM signals to generate and PM mode in addition, a 217 Hz signal with 12.5% duty cycle to simulate the handshake signal in the GSM mobile network. Also ideal for users who, although they have a spectrum analyzer, but no RF signal generator. The TBDA versions without its own modulation opportunity to bring the same output power and are designed for the control by RF signal generator.

RF power amplifier

The models TBMDA2 , TBMDA3 and TBMDA4 are modulated power amplifier for immunity tests. Like the TBMDA1, the amplifier for controlling via tracking generator are designed. Per switch the modulation modes can 1 kHz AM or PM signal are activated, and in the PM mode, a 217 Hz signal at 12.5% duty cycle can be generated in addition. The models of the TBLPA series are highly linear power amplifier for universal use in RF technology.
