Renaissance has developed a new drop-in isolator to handle 15 W of reflected power in a compact size of 0.5” x 0.75” at X-Band frequencies. Covering 7.9 TO 8.4 GHz, this isolator provides a VSWR of 1.25:1 at input and output ports with loss of 0.5 dB and isolation of 20 dB over -40 to +85 C. It is specifically designed for Mobile Satellite architecture.
The HMPA and HHPA Series of Medium and High Power Amplifiers covers select bands from 20 to 100 GHz. A wide variety of gain and bandwidth combinations are available to provide the designer with a solution for most applications. Custom designs are available and in many cases NRE is not required.
RFMW, Ltd. announces design, sales support and availability of TriQuint Semiconductor’s TAT8804D1H ultra-linear GaAs amplifier MMIC intended for output stage amplification in CATV infrastructure applications where flat gain and low distortion are key considerations.
Richardson RFPD, Inc. introduces a new 50 V gallium nitride on silicon carbide (GaN on SiC) RF power high-electron-mobility transistor (HEMT) from Microsemi Corporation (Microsemi). The 0912GN-650V is internally-matched and capable of providing over 17 dB gain, 650 W of pulsed RF output power at 128 μs pulse width and 10% duty factor across the 960 to 1215 MHz band.
RFMW, Ltd. announces design and sales support for Scintera Networks SC1894 radio frequency power amplifier linearizer (RFPAL). As power amplifiers are driven into saturation they increase in both efficiency and distortion. The SC1894 injects a correction signal at the input of the PA in order to minimize distortion at the output of the PA. The result is higher output power from the PA and increased efficiency.
Model 30HM1G6AB-45 is a compact, wide-band, Class AB hybrid solid state power amplifier module that instantaneously covers 1 to 6 GHz. It operates from a single DC voltage and provides 48 dB of typical gain with excellent gain flatness, noise figure and low intermodulation distortion.
FEKO Suite 6.3 delivers several new solver features as well as improvements of the user interface. FEKO users can find more detail in the FEKO Suite 6.3 download area or consult the release notes which can be found in the FEKO Suite 6.3 installation directory.
Spacek Labs model M80-5X2B is an E-band mixer covering the two radio bands of 71 to 76 GHz and 81 to 86 GHz. The mixer includes an integrated LO doubler, so that the customer need only supply a 39 GHz source with +16 dBm of power. Spacek Labs can also supply a phase-locked source with the assembly. The conversion loss over the band is 6 dB typ and 10 dB max, with an IF frequency range of 2 to 8 GHz. The input P1dB is -6 dBm typ, and the bias is +12 VDC @ 10 mA.
PMI model number PIQ-85M18G-360/20-CD-2 is a vector modulator covering the frequency range of 85 MHz to 18 GHz. This unit provides an attenuator resolution of 0.08 dB and a phase shift resolution of 0.703125. The attenuation is phase invariant and the phase is amplitude invariant making it ideal for nulling unwanted signals. The unit can be specifically calibrated for any number of 100 MHz bands within the frequency range.
