Transmission Line Pulse Testing
Transmission Line Pulse testing, or TLP testing, is a method for semiconductor characterization of Electrostatic Discharge (ESD) protection structures. In the Transmission Line Pulse test, high current pulses are applied to the pin under test (PUT) at successively higher levels through a coaxial cable of specified length. The applied pulses are of a current amplitude and duration representative of the Human Body Model (HBM) event (or a Charged Device Model – CDM – event in the case of Very Fast TLP, or VF-TLP).

Transmission Line Probes
Transmission line probes are a special type of passive probe designed for use at very high frequencies. They replace the high impedance probe cable found in a traditional passive probe with a precision transmission line, with a characteristic impedance that matches the oscilloscope input (50 Ohm). This greatly reduces the input capacitance to a fraction of a picofarad, minimizing the loading of high frequency signals. A matching network at the tip increases the DC input resistance. While they have lower DC input resistance than a traditional passive probe (usually 500 Ohm) to 1kOhm), the input impedance of these probes remains nearly constant over their entire frequency range. A traditional /10 passive probe will have a 10 MOhm) input impedance at DC, however this impedance drops rapidly with frequency, passing below the input impedance of a transmission line probe at less than 100 MHz.

Impedance Measurement
CITS880s
Finer geometries and thinner copper can present a challenge for fabricators measuring impedance on leading edge PCBs. The CITS880s answers that challenge with the introduction of Launch Point Extrapolation (LPE). LPE extrapolates the TDR response back to a point close to the start of the transmission line effectively allowing to users more accurately to measure the instantaneous or incident impedance of the line.

Directional Couplers
Pasternack directional coupler category is passive devices that couple part of the transmission power in a transmission line. Our directional coupler series provides the bandwidth, high directivity and higher power that engineers need for their most demanding application designs. RF directional couplers often use two transmission lines set close together so that energy passing through one is coupled to the other. Many Pasternack directional coupler components are RoHS and REACH compliant. RF directional couplers are available with 4.1/9.5, 4.3-10, 7/16 DIN, Type N or SMA connectors. Our directional coupler line has 6dB, 10dB, 15dB, 16dB, 20dB, 30dB or 35dB coupling values. Power ratings of our typical and high power directional couplers range from 25 Watts to 70 Watts. Directional coupler frequency range of this product design is from 1 GHz to 8 GHz. As with our other over 40,000 RF, microwave and millimeter wave components from Pasternack, this directional coupler series is in-stock. Not only are these couplers in directional design in stock, they also will ship the same day as they are purchased.

Resistors
A passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. High-power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls, in power distribution systems, or as test loads for generators. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity.
