Components

Millimeter-wave Balanced Mixers
Ducommun Technologies offers balanced mixers that are available in six waveguide bands to cover the frequency spectrum from 26.5 to 110 GHz. These mixers employ high power performance GaAs Schottky beamlead diodes and balanced configuration to produce superior performance and a moderate LO pumping level. The mixers are designed for full RF waveguide band operation with extremely wide IF bandwidth. Typical conversion loss for these mixers is 5 to 10 dB. Ducommun mixers can be used for test equipment, communication systems and radar receivers where frequency down conversion is required.

Material

Laminates for High Power Applications
TSM-DS3 is the newest addition to the TSM-DS family of thermally stable, industry-leading low loss cores. This ceramic-filled laminate with low (~5 percent) fiberglass content has a dissipation factor of 0.0011 at 10 GHz and thermal conductivity of 0.65 W/M K. In addition to high power applications, TSM-DS3 was developed to have very low coefficients of thermal expansion for demanding thermal cycling. RF-35TC is suited for high power applications where every 1/10th of a dB is critical and the PWB substrate must diffuse heat away from transmission lines and surface-mount components. The low z axis coefficient of thermal expansion and temperature stable Dk make RF-35TC ideal for narrowband and broadband overlay couplers. RF-35TC has a dissipation factor of 0.0011 at 10 GHz and thermal conductivity of 0.92 W/M K (with 1 oz copper cladding).

Test Equipment

Testing For W-CDMA/GSM Devices
The MX848001E-17 Simultaneous 64QAM/MIMO option enables the MD8480c Signaling tester to conduct protocol-based testing on new W-CDMA/GSM wireless devices that incorporate this feature. Simultaneous 64QAM/MIMO offers network operators and consumers 42 MB/s download speeds similar to DC-HSDPA, with the advantage that spectrum is conserved through use of a single 5 MHz channel rather than the two channels required for DC-HSDPA. With this option, the MD8480C now supports all W-CDMA data rates, from 12.2 kB/s voice calls to 42 MB/s data calls, including new category 17, 18, 19 and 20. The MD8480C is available in a range of configurations starting at $109,290, and the MX848001E-17 software option can be easily added to MD8480Cs with E-version base station cards. Upgrades to MD8480C testers with C-version base station cards and the MD8480B signaling tester are available.
