Macom Technology Solutions Holdings Inc.

Macom Technology Solutions Holdings Inc.

At MACOM we offer 18 - 40 GHz bias networks suitable for DC biasing of PIN diode control circuits. Our bias networks function as both RF to DC decoupling networks, as well as a DC return. These bias networks can also be used as bi-directional reactive couplers for Schottky detector circuits in multimarket applications.

The input section features the unique servo bias input circuitry with a standard TA5M type jack for use with electret lavaliere mics, dynamic mics, or line level signals. A DSP-controlled analog audio limiter is employed before the A-D converter. The limiter has a range of more than 30 dB for excellent overload protection and a dual release envelope that makes the limiter acoustically transparent while maintaining low distortion. The limiter recovers quickly from brief transients, with no audible side effects, and also recovers slowly from sustained high levels to keep audio distortion low while preserving short term dynamics.

Keysight Technologies

11970Q - Keysight Technologies

The Keysight 11970Q waveguide mixer is a general-purpose harmonic mixer employing a dual-diode design to achieve flat frequency response and low conversion loss. These are achieved without external dc bias or tuning stubs. Manual operation and computer-controlled hardware operation are simplified because mixer bias and tuning adjustment are not required.

Praxsym

Praxsym

Low Noise Pre-Amplifier and companion external low noise amplifier (LNA) are used to amplify low level microwave signals. The Pre-Amplifier contains an AC/DC power supply, internal low noise amplifier, and a bias tee to source a DC bias voltage on the RF input connector.To overcome cable loss between the test antenna and the Pre-Amplifier assembly, a remote low noise amplifier (LNA) is mounted directly onto the 10 GHz antenna. A bias tee inside the Pre-Amplifier chassis powers the remote LNA through the coax cable interconnecting the pre-amplifier and the 10 GHz test antenna.

Pulse Characterization Sensors

MKS Ophir

MKS Ophir

Pulse Characterization Sensors provide the ability to see and measure the temporal characteristics of pulsed and CW laser beams. Ophir Fast Photodiode Detectors are designed to convert optical signals into electrical signals which are then measured with third-party instrumentation such as oscilloscopes and spectrum analyzers. Accessories are available to connect to IS6 integrating spheres or fiber optic cables. Attenuating filter accessories are also available to increase their dynamic range. Different models offer silicon, UV enhanced silicon and InGaAs PIN photodiodes, covering a combined spectral range of 193 nm to 1700 nm. Rise times range from 25 picoseconds to 3 nanoseconds. The fast rise times are achieved by an internal reverse bias voltage circuit. Power is supplied by internal batteries and/or an external power supply depending on the model. Detectors should be connected to a 50Ω impedance in order to maintain their nominal rise times. They can be connected to higher impedance loads, but this will result in a significant increase in the rise time. If higher output voltage is required, it is recommended to connect the detector to a trans-impedance amplifier with an Input impedance of 50Ω
