Model SWF-60390350-28-L1 is a custom designed Ka-Band waveguide lowpass filter. The filter features low insertion loss and high rejection. The filter shows 1.2 dB maximum insertion loss from 26 to 60 GHz and greater than 50 dB rejection in the frequency range of 90 to 145 GHz.
Model SFS-60390315-10VFSF-S1 is an E-Band, subharmonically pumped mixer. The mixer employs high performance GaAs Schottky beamlead diodes, balanced configuration to produce superior RF performance. The subharmonically pumped mixer is capable for full RF waveguide band operation for RF frequencies from 60 to 90 GHz with half of the LO frequency: 30.0 to 45.0 GHz.
Linear Technology Corp. announces the LT3081, a rugged 1.5 A wide input voltage range linear regulator with key usability, monitoring and protection features. The device has an extended safe operating area (SOA) compared to existing regulators, making it ideal for high input-to-output voltage and high output current applications where older regulators limit the output.
PFEM-9D4G-CD-1 is a multi-function module that provides amplification, switching and filtering within the frequency band of 9410 MHz. This module provides two input channels and is switchable to a common output. This model is designed to offer multiple gain level selection, high channel to channel isolation and fast switching speeds.
PMI Model No. LM-0518-10-1W-SHS-2-M-1218 is a high power limiter that operates from 12.0 to 18.0GHz. This limiter handles 100 W peak power with a pulse width of 1usec. The insertion loss is only 1.5dB typically and has a VSWR of 2.0:1 maximum.
RFMW Ltd. announces design and sales support for IXYS RF model IXRFD631, a high-current CMOS gate driver specifically designed to drive MOSFETs in Class D and E HF RF applications as well as other applications requiring ultrafast rise and fall times or short minimum pulse widths.
PMI Model No. P2T-1G18G-10-R-5V-SFF-HIP10W-HERM is a hermetically sealed, reflective, single pole, two throw pin diode switch that operates over the 1.0 to 18.0GHz frequency range. This model is capable of handling an input power level of 5 WCW while providing switching speeds of less than 40ns typically.
RFMW, Ltd. announces design and sales support for two new Peregrine Semiconductor SP5T switches targeting T/R and filter-band switching in Land Mobile Radio (LMR) and Military radio applications where high power handling (17W) is required. Both the PE42850 and PE42851 feature low power consumption of 130 microamperes which helps to extend battery life in mobile applications.
Linear Technology announces the high temperature H-grade (-40° C to 150° C junction temperature) and high reliability MP-grade (-55° C to 150° C) version of the LTC3115-1 in a 20-lead thermally enhanced TSSOP package. The LTC3115-1 is a synchronous buck-boost converter that delivers up to 2 A of continuous output current from a wide range of power sources from single-cell Li-Ion to 24/28 V industrial rails to 40 V automotive inputs.
