Mercury Systems' control components capabilities include custom control devices and multi-function assemblies; purposely built to suit your application needs. These may combine active and passive circuit elements, such as switch filters, switched attenuators, phase shift switches or complete front-ends.
Laser Services Inc., an ISO and AS9100 registered laser job shop, has announced the addition of a new metrology system for measuring precision parts. The Boulder Imaging ML Series metrology system measures and records single or multiple high-precision, two-dimensional parts in seconds, dramatically reduces inspection time.
Custom MMIC has added two new low noise amplifiers, the CMD167 and the CMD167P3, to their growing product line. The CMD167 is a highly efficient, ultra low noise GaAs MMIC amplifier that operates from 10 to 17 GHz. The CMD167P3 is the packaged version of the amplifier which operates from 8 to 16 GHz.
RFMW Ltd. announces application and sales support for the Telemakus TEP4000-5 digital phase shifter. This laboratory quality phase shifter has a minimum phase range of 360 degrees with 12-bit, 0.25 degree resolution and operates over the bandwidth of 2 to 4 GHz. Maximum RF input for linear operation is +6 dBm but the device can handle up to +20 dBm. Typical insertion loss through the TEP4000-5 is only 5 dB.
Linear Technology Corporation introduces the LTC3874, a dual phase synchronous step-down slave controller that generates currents up to 300 A when paired with a companion master controller by extending the phase count in multiphase applications. Compatible master controllers include the LTC3866, LTC3875 and LTC3774, which all have true current-mode control.
AtlanTecRF launches its first ever comprehensive range of digitally controlled PIN attenuators. The ADA series covers frequencies from 500 MHz to 40 GHz in 17 models.
RFMW Ltd. announces design and sales support fortwo S-band power amplifiers from TriQuint. The TGA2583 and TGA2585 cover the frequency range of 2.7 to 3.7 GHz with 10 and 18 W of saturated output power respectively. Both TriQuint devices offer power added efficiency of 54% with a small signal gain of 33 dB.
Renaissance has released a new L-Band 4.5 kW peak power drop-in circulator operating from 1 to 1.12 GHz. With insertion loss of less than 0.2 dB and with return loss and isolation over 23 dB, the circulator is ideal to duplex an antenna with HPA and a receiver. This circulator has been customized to withstand 50 W of forward and 100 W of reverse power at the same instance without arcing or corona failures.
Renaissance has developed a new low cost, high power, drop-in isolator to protect expensive amplifiers from unwanted reflected power levels at S band frequencies. Covering 2.7 to 2.9 GHz, this isolator provides a VSWR of 1.25:1 at input and output ports with loss of 0.4 dB and isolation of 20 dB over -30 to +85 C.
HLNA Series of low noise amplifiers covers the frequency ranges 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. MMIC technology is employed for high reliability and repeatability.
