Multi-channel radio module
01 June, 2008 | Supplied by: RF Modules Australia
Radiometrix has introduced an addition to its LMT2/LMR2 transmitter/receiver series. Making use of the 458.525-459.1 MHz British frequency band (instead of the 433.875-434.650 MHz EU band used in previous versions), these higher power modules increase the distance over which they can communicate to 1 km, allowing engineers to enhance systems that previously had insufficient range (or insufficient link margin).
RF/DC crossover
01 June, 2008 | Supplied by: ASD Technology Pty Ltd
Florida RF labs has released the RF/RF and RF/DC crossover with an integrated 2 W attenuator.
1000 V screwdriver set

The Ergo 1000 V screwdriver set from Bacho includes four slotted and three PoziDrive tipped screwdrivers with colour-coded handles to aid identification.
Vibration-resistant module
01 June, 2008 | Supplied by: RF Modules Australia
Aimed at applications where RF engineers need to consider the interference effects of nearby vibrating machinery, Radiometrix has developed the HVR2 receiver module, a high vibration-resistant version of the RLC2 that uses the company’s direct digital synthesiser (DDS) local oscillator design to make it almost totally immune to mechanical vibrations at frequencies below 500 Hz.
Amplifier drivers
01 June, 2008 | Supplied by: ASD Technology Pty Ltd
Miteq has introduced a range of linear SSPA drivers. Three models cover all the common satellite communication bands, AMFLD-05700850-60-16P for C-/X-band, AMFLD-12501850-60-16P for Ku-/DBS-band and AMFLD-27003100-60-12P for Ka-band.
VC oscillator
01 June, 2008 | Supplied by: Richardson Electronics Pty Ltd
Crystek’s CVCO55CC-1930-2110 VCO operates from 1930 to 2110 MHz with a control voltage range of 0.5-18. The VCO features a typical phase noise of -110 dBc/Hz at 10 kHz offset and has good linearity.
RF modules
01 June, 2008 | Supplied by: Nu Horizons Electronics Asia Pty Ltd
