Linear Technology Corp. announces the LTC3886, a 60 V input dual output synchronous step-down DC/DC controller with programmable loop compensation and I²C-based PMBus interface. This controller employs a constant-frequency, current-mode architecture with programmable output voltage up to 13.8 V. The LTC3886 is ideal for harsh environments requiring a high input voltage range commonly found in factory automation, industrial, medical, communications and more.
RFMW Ltd. announces design and sales support a high dynamic range, analog controlled, variable gain amplifier (VGA) operating from 0.7 to 2.8 GHz. The Qorvo TQC9074 offers 30 dB of analog controlled gain variation range and an OIP3 of 41.5 dBm. Applications include remote radio heads and small cell infrastructure. The TQC9074 draws 235 mA from a 5 V supply. Users can access each stage of the module for performance enhancements in their design.
KRYTAR Inc. announces the continued expansion of its growing line of directional couplers with a new model offering 6 dB of coupling over the frequency range of 10 to 67 GHz, in a single, compact and lightweight package. The latest addition enhances the selection of multi-purpose, stripline designs that exhibit excellent coupling over a broadband frequency range of 10 to 67 GHz.
Pasternack introduces a large portfolio of in-stock general purpose multi-market coaxial packaged electromechanical switches for RF, microwave and millimeter wave applications. These new electromechanical switches are uniquely qualified for use in numerous applications including military communications, radar, commercial and military aviation, SATCOM, test & instrumentation, medical equipment and others.
Linear Technology announces the LTC5549, a double-balanced mixer that can operate either as an upconverter or downconverter, with a very wide RF frequency range from 2 to 14 GHz. The LTC5549 offers exceptionally high linearity of 24.4 dBm IIP3 at 9 GHz. The LTC5549 enables efficient microwave transmitter and receiver designs with an integrated LO buffer that needs only a 0 dBm drive level, effectively eliminating an external high power LO amplifier circuit.
The RM022020 features Qorvo’s patented Spatium™ combining technology to provide unprecedented performance in a general purpose laboratory bench top amplifier for applications that include lab work, test and measurement, load pull, EMI test, and anechoic chambers and test ranges. It is suitable for use a driver/booster amplifier, enabling more power incident upon the device under test (DUT).
Passive Plus Inc. (PPI) manufactures high quality, high power passive components using state-of-the-art manufacturing techniques. Specializing in Magnetic & Non-Magnetic HI-Q Capacitors product lines, PPI supplies reliable quality components to the aerospace, telecommunications, medical semiconductor, and military industries.
RFMW Ltd. announces design and sales support for low passive inter-modulation (PIM) attenuators from EMC Technology. When comparing the new 33P7024 (100 W) series to standard attenuators the difference is typically ≥ 10 dBc. The 33P702403.00F offers 3dB of attenuation while the 33P702430.00F offers 30dB attenuation. Designed for demanding infrastructure applications, both EMC’s 33P702403.00F and 33P702430.00F operate to 2.7 GHz.
Model SBL-5037533060-1212-E1 is a low noise amplifier covering the full waveguide band from 50 to 75 GHz with small signal gain of 30 dB and 6.0 dB noise figure. The amplifier also exhibits +10 dBm typical P-1 dB output powers. It draws about 120 mA current from a single DC power supply in the range of +8 to +12 volts.
RFMW Ltd. announces design and sales support for two highly selective, LowDriftä BAW filters created for Band 3 uplink and downlink applications. Qorvo’s TQQ0303 provides 75 MHz of usable bandwidth and up to 1 W power handling for Band 3 downlink applications. The Qorvo TQQ0302 offers similar bandwidth and power handling for Band 3 uplink. Both TQQ0303 and TQQ0302 offer single-input, single-output operation.
