The VX–805's phase noise is optimized for wireless base stations. Base station architectures are getting smaller and as they do, board densities are increasing. As a result the phase noise performance of the transceiver VCXO is critical for these applications.
RFMW Ltd. announces design and sales support for Peregrine Semiconductor’s PE42424, a SPDT switch operating from 100 MHz to 6 GHz. The PE42424 uses Peregrine’s HaRP technology to create a 50 ohm, reflective switch for high power, 802.11a/b/g/n/ac applications. Handling up to 8 W of transmit power, the PE42424 supports switching applications for outdoor Wi-Fi access points or WiFi enabled small cells.
Vectron's VS–703 voltage controlled SAW oscillator (VCSO) is a SAW stabilized, low phase noise, high frequency oscillator with CML compatible outputs (fN < 1.2 GHz), differential sine wave outputs (fN > 1.2 GHz), operating at 3.3 volt supply, hermetically sealed 5 x 7 ceramic package.
Richardson RFPD Inc. announced the availability and full design support capabilities for a new 2-way, 90-degree power splitter from M/A-COM Technology Solutions. The MAPD-011018 operates from 5 to 250 MHz and offers excellent temperature stability, low power loss, high signal separation, and even power distribution.
Linear Technology Corp. introduces the LTM4634, a triple output step-down µModule® (micromodule) regulator in a 15 mm x 15 mm x 5.01 mm BGA package with integrated heat sink. The thermally efficient package enables the LTM4634 to deliver full current on all three outputs (5A, 5A, and 4A), more than 70 W of output power at 65° C ambient with 200 LFM airflow.
The VT-820 Temperature Compensated Crystal Oscillator (TCXO) is a quartz stabilized, clipped sine wave output, analog temperature compensated oscillator, operating off either 2.8, 3.0 or 3.3 volt supply, hermetically sealed 3.2 x 2.5 ceramic package.
RFMW Ltd. announces design and sales support for four new high-linearity, low noise gain blocks from TriQuint. Offered as DIE, they target hybrid assembly designs requiring the highest level of performance unencumbered by package parasitics. All devices cover applications from 0.05 to 4 GHz such as commercial and military radar receivers, EW, and communication LNA designs.
The TX–707 Series TCXO combines innovative manufacturing and the latest technology to provide low phase noise and excellent g–sensitivity. The fully hermetic assembly includes a dual crystal circuit to cancel opposing g–sensitivity vectors enclosed in a 5x7 mm ceramic package.
Linear Technology Corp. introduces the LTC3807, a low quiescent current synchronous step-down DC/DC controller that draws only 50 µA in standby mode with the output voltage in regulation. The LTC3807 has powerful 1.1 Ohm on-chip MOSFET gate drivers. It operates with a selectable fixed frequency between 50 and 900 kHz and is synchronizable to an external clock ranging from 75 to 850 kHz.
