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.
Linear Technology announces the LTM4644 quad output step-down µModule® (micromodule) regulator configurable as a single (16A), dual (12A, 4A or 8A, 8A), triple (8A, 4A, 4A) or quad (4A each) output regulator. This flexibility enables system designers to rely on one simple and compact µModule regulator for the variety of voltage and load current requirements of FPGAs, ASICs and microprocessors.
The AE70NS2067 notch filter has a notch bandwidth of 68 MHz to 72 MHz, rejection of at least 30 dB, a low-side passband of DC to 64 MHz and high-side passband 76 to 150 MHz. Insertion loss is less than 1 dB, and the filter measures 4 x 1.25 x 0.75 in. and uses SMA female connectors.
The AE14625-15250DB5370-LNA combines a high-performance duplexer with a low-noise amplifier with excellent noise performance in a compact module. The duplexer’s band 1 is 14.4 to 14.83 GHz, band 2 is 15.15 to 15.35 GHz, insertion loss is less than 2 dB, rejection is at least 60 dB, and power handling ability is 150 W.
The AM1500PD902 two-way power divider cover 800 to 2200 MHz with insertion loss of 0.5 dB, isolation of at least 18 dB, amplitude balance 0.5 dB, phase balance of 5 deg., and VSWR of 1.4:1. It will handle 100 W CW, uses Type-N female connectors, and measures 2.1 x 2.1 x 1 in.
