Broadband Antenna
Vivaldi
-
The dbDIRECT Broadband Antenna features a broad frequency range of operation, high gain, small form factor and directional radiation pattern, making it highly attractive for widespread use in test and measurement of emerging wireless technology devices and radars. Contrary to conventional Vivaldi antennas limited to operating only at higher frequencies, the dbDIRECT Broadband Antenna design is optimized to operate at a frequency as low as 700 MHz up to 6 GHz. This lightweight and compact antenna design provides excellent matching over a broad frequency range.The antenna is designed to be placed in a DVTEST's portable anechoic chamber such as the dbSAFE enclosures for OTA (Over the Air) testing of DUTs. The antennas can be mounted in fixed positions to facilitate repeatable results. When used in conjunction with a rotary positioning mechanism, customers are able to detect the highest point of power sensitivity for enhanced accuracy and repeatability in measurements. In this configuration, both the antennas and DUTs can be positioned in order to facilitate the measurement.

Broadband Detectors
-
These waveguide bandwidth detectors use silicon beam lead diodes on a planar stripline circuit to obtain an extremely rugged and compact device. Most millimeter wave broadband detectors have very poor VSWR due to the difficulty in obtaining a good wideband impedance match to the diode. To overcome this problem, these detectors utilize two diodes and an internal matched termination and 3 dB hybrid as shown below. This circuit allows a VSWR of 2.0 or better over a full waveguide bandwidth for most of these detectors. Detectors for waveguides WR-8 and smaller use a single zero bias GaAs diode. The high sensitivity zero bias GaAs diodes can also be special ordered for use at lower frequencies when highest sensitivity is required.

SSPAs / LNAs / Broadband
-
SSPAs based on the latest Galium Nitride (GaN) technology offer the best combination of high peak powers, high reliability, high efficiency, and soft degradation. High efficiency and high power are hallmarks of GaN technology, enabling SSPAs to challenge traditional tube-based amplifiers across the design spectrum. In addition the long lifetime from these devices, combined with the gradual degradation should individual devices fail, provide unparalleled service lifetime. Techniques such as bias modulation and linearization provide even better prime-power efficiency while still meeting the demanding requirements of pulsed or CW applications.
