SemiGen Inc., an ISO and ITAR registered RF/Microwave assembly, automated PCB manufacturing, and RF Supply Center, offers PIN diodes that feature low capacitance and resistance, high reliability, and easy bonding with F.A.C. mesas.
The Reliant SwitchTM is a 1×6 bidirectional coaxial switch with an operating frequency from DC to 26.5 GHz, which covers the typical 6 GHz test range and beyond for high-speed testing. This switch is designed with a high isolation of 100 dB (up to 4 GHz) to maintain RF consistency between port-to-port testing and can sustain a guaranteed insertion loss repeatability of 0.03 dB across the entire frequency band.
Richardson RFPD Inc. announces immediate availability and full design support capabilities for a select group of new low-cost products for wireless infrastructure and Aerospace & Defense applications from Skyworks Solutions, Inc. Devices include LNAs with ultra-low noise figures of 0.23 dB, as well as PAs offering 2 W P1 dB and +25 dBm linear Pout, and switches handling up to 150 W input power.
RFMW Ltd. announces design and sales support for the PE4312, 6-bit digital step attenuator from Peregrine Semiconductor. The PE4312 is designed for use in wireless infrastructure, portable radios and broadband infrastructure applications from 1 MHz to 4 GHz. Key features include excellent attenuation accuracy +/- (0.15 + 2% of attn at 2.2 GHz) and low insertion loss.
Linear Technology announces the LTC3637, a 76 V input-capable high efficiency buck converter that delivers up to 1 A of continuous output current. It operates from an input voltage range of 4 to 76 V, making it ideal for telecom, industrial, avionic and automotive applications. The LTC3637 utilizes a programmable peak current-mode design to optimize efficiency over a broad range of output currents.
Agilent Technologies Inc. introduced its next-generation real-time peak detection as one of the additional functionalities for its award-winning PCIe high-speed digitizers, starting with the U5303A 12-bit digitizer. Several data processing algorithms can be hosted at the same time in the FPGA, allowing easy and fast switching from one to the other using the high-speed digitizer driver.
RFMW Ltd. announces design and sales support for the PE43705, a 7-bit, 31.75 dB digital step attenuator from Peregrine Semiconductor. The PE43705 offers an extremely wide operational frequency range of 50 MHz to 8 GHz. Internal circuitry manages unequal ON/OFF switch times providing a “glitch safe” design by eliminating the unknown attenuation issue that plagues other DSAs.
This new PXI 10A power multiplexer (model 40-661) is available in a variety of configurations ranging from 8 off 4:1 multiplexers to 1 off 32:1 multiplexer. Each multiplexer is capable of hot switching up to 10 A at 30 VDC and has a maximum DC hot switch rating of 125 VDC. AC signals up to 250 VAC at 10 A can be switched. For cold switching applications the 40 to 661 is capable of withstanding 400 VDC.
AtlanTecRF has introduced two new models of Zero Bias Schottky Detectors with high sensitivity and a wide operating temperature range. The first two frequency ranges offered are 10 MHz to 18 GHz and 2.0 to 8.0 GHz, both with sensitivity of 500 mV/mW and TSS of -50 dBm. Flatness over the 10 MHz to 18 GHz frequency band is +/-1.25 dB max and VSWR for such a unit is 2.0:1.
The HAFM Series of active multipliers is available in models ranging from 30 to 100 GHz. A wide variety of multiplication factors from X2 up to X6 provide the customer with design flexibility for many applications. Basic multiplier circuits can be cascaded to achieve higher order multiplication factors.
