Wideband Downconverter RFIC is Ideal For Multi-Standard Diversity Receivers!

Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has released a new Broadband High IP3 Downconverter RFIC which operates from 700 to 3500 MHz. The HMC1090LP3E is ideal for space constrained frequency conversion applications in wireless infrastructure equipment such as base transceiver stations, remote radio units, small cells and repeaters.

The HMC1090LP3E is a high linearity downconverting mixer which is optimized for multi-standard diversity receiver applications where low power consumption and small size are required. This highly integrated RFIC features a wideband limiting LO amplifier and can be used in any 3GPP operating band from 700 to 3500 MHz. Unlike conventional narrow-band downconverter RFICs, the HMC1090LP3E supports both high-side and low-side LO injection over the entire RF band.

The HMC1090LP3E integrates LO and IF amplifiers, LO and RF baluns and a wideband passive mixer core with bias control. The unique architecture of this converter provides excellent LO/RF, LO/IF, and RF/IF isolations, while the RF and LO input ports are internally matched to 50Ω. The HMC1090LP3E exhibits noise figure as low as 8.5 dB and input IP3 up to +26 dBm making it ideal for demanding high linearity applications. For narrow-band applications, the input IP3 performance of the HMC1090LP3E can be further optimized with simple external matching.

Consuming only 0.9W of DC power, the HMC1090LP3E offers a very fast enable function which provides additional power conservation options in time division duplex (TDD) applications. The HMC1090LP3E is housed in a compact RoHS compliant, 3 x 3 mm plastic QFN package. The unique converter is also available in dual channel format as the HMC990LP4E.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
