Bulk Acoustic Wave Technology
BAW
-
Macom Technology Solutions Holdings Inc.
MACOM’s BAW product portfolio is ideal for high performance Industrial, Aerospace, Defense, and Communications applications that require critical frequency filtering. Our high-performance RF filters enable our customers manage signal integrity in the 1 to 6 GHz frequency range. Bulk Acoustic Wave Resonators consist of two metal electrodes above and below a layer of a piezoelectric material. The piezoelectric material converts an electrical signal to a mechanical signal and vice versa. The metal electrodes provide the connections to/from the piezo material. The frequency at which resonance occurs depends on the thickness of the combined metal-piezo-metal stack. Advances in thin-film piezoelectric fabrication have enabled BAW resonators to meet RF filtering challenges up to 6000 MHz using standard MEMS fabrication process. High-performance BAW resonators-based RF filters are made of piezoelectric material having high Q-factor (>3000) and high coupling coefficient. Currently, no competitive technology provides the same high performance for RF filter applications when compared to BAW resonator-based RF filter up to 6000 MHz for the same size and cost.

Current Transformers
-
The Institute of Electrical and Electronic Engineers defines a current transformer (IEEE Std C57.13) as “a transformer intended to reproduce in its secondary circuit, in a definite and known proportion, the current of its primary circuit with the phase relations substantially preserved”. Its primary winding is connected in series with the conductor carrying the current to be measured or to be controlled and its secondary winding is connected to the measuring, protection or control devices. Osborne designs and manufactures current transformers which are used for instrumentation applications, others which are used for power system synchronizing applications and others which are used in protection circuit application. They have been designed to meet specified current ratios, burden impedance and transformation errors.

Current Pulsers and Laser Diode Drivers (Pulsed Current)
-
These instruments generate current pulses whose amplitude is largely independent of the load voltage. This makes them ideal for pulsing device whose voltage may vary with time (for instance, the voltage drop of laser diodes may vary with temperature, or explosive squibs which change impedance during ignition). This voltage independence is a trade-off with speed. If faster rise times are required, consider using pulsed voltage instruments instead.

Injection Transformer
J2100A
-
The injection transformer is presently the prevalent method for connecting the network analyzer to the circuit being tested, and is primarily used for control loop stability measurements. The goal of the transformer is to inject a signal into the control loop being measured, without impacting the performance of the loop. In order to accomplish this to a reasonable degree, The transformer is isolated and therefore is capable of floating on a high voltage, such as a Power Factor Corrector (PFC), which is often close to 400VDC. Measuring voltages that exceed the voltage rating of the FRA inputs require attenuation probes.

voltage-output, current-sensing amplifier family that integrates an internal shunt resistor to enable high-accuracy current measurements at common-mode voltages that can vary from 0 V to 36 V, independent of the supply voltage. The device is a bidirectional, low- or high-side current-shunt monitor that allows an external reference to be used to measure current flowing in both directions through the internal current-sensing resistor sensor. The integration of the precision current-sensing resistor provides calibration equivalent measurement accuracy with ultra-low temperature drift performance and ensures an optimized Kelvin layout for the sensing resistor is always obtained.

Primary Injection Test Systems
-
Primary current injection testing is utilised in high current/high voltage scenarios found at large electrical installations such as substations. A large current (between 100A and 20,000A depending on system specifications and test requirements) is injected directly on the primary side of the electrical system such as a circuit breaker. The objective of the test is to identify how the system operates under various levels of current load.
