RF Amplifiers Bias Controllers
RF amplifier bias controllers generate a regulated drain voltage and actively adjusts the gate voltage of an external amplifier to achieve constant bias current. It can be used to bias any enhancement and depletion type amplifier operating in Class-A regime with drain voltages (VDRAIN) as specified. These devices achieve excellent bias stability over supply, temperature and process variations, and eliminates the required calibration procedures used to prevent RF performance degradation due to such variations.

Ultra Low Level DC Voltage Amplifiers
The EM A10 is a low level amplifier module for sensitive measurements, data collection and systems, where signals below 1 nanovolt may be measured. It is ideal for the input unit for precision voltage measuring systems, requiring voltage sensitivity for measuring low noise and low impedance sources. The noise level of the A10 is equivalent to a perfect resistor of about 20 ohms. When used with a digital voltmeter, steady one nanovolt digits may be displayed, with a response time constant of less than a second. The input voltage stability of the A10 is very high, with the drift around a nanovolt per degree C. The input connectors are made from pure copper. The input impedance is very high, and is time dependent, determined by the loop gain.

Amplifier, Switch and Test Box
CLIOQC Model V
The QCBOX Model 5 is a non-conventional unit designed to fulfil actual and future needs of an electro-acoustical analyzer like the CLIO system. It is USB linked to a PC and can be configured, with dedicated software controls, to assist frequency response and impedance measurements or to perform DC measurements. Using it for frequency response measurements acts as 50W power amplifier to drive the speaker or network under test while routing one-of-four inputs to the analyzer as well the current sensing output. The four inputs are able to provide a phantom power supply both for Audiomatica or general purpose microphones (0-24 V range, software controlled). Impedance measurements can be done either switching the D.U.T.’s load across the analyzer’s input or using a dedicated output, ISENSE, thus allowing impedance measurements in constant voltage mode as well voice coil current distortion analysis. An internal ADC measures the DC current into the voice coil. Thanks to an internal software controlled voltage generator the speaker can be driven with a superimposed DC voltage (±20V), allowing for measurements of large signal parameters. Two ADC converters with a ±2.5 V and ±5 V are available at inputs 3 and 4 to measure the displacement with a laser sensor or any other DC signal. A dedicated digital input handles an external foot pedal switch (or TTL signal) to be connected and triggers QC operations. A 6 bit output – 5 bit input TTL digital port is available to interface the QCBOX and driving software with external hardware (like turntables for example).The QCBOX Model 5 finds use both in laboratory for R&D applications and in production lines setups.
