Voltage-Controlled Oscillator Is RoHS Compliant

Z-Communications has announced an RoHS-compliant Voltage-Controlled Oscillator (VCO), model ZRO2407A1LF in S-band. The ZRO2407A1LF operates at 2,400-2,415MHz with a tuning-voltage range of 0.5-4.5V DC. This VCO features a typical phase noise of -115dBc/Hz at 10KHz offset and a typical tuning sensitivity of 14MHz/V.

It is designed to deliver a typical output power of 3dBm at 5V DC supply, while drawing 21mA (typical) over a temperature range of -40 to 85C. This VCO features typical second harmonic suppression of -18dBc and comes in Z-Comm's standard MINI-16-SM package, measuring 0.5 x 0.5 x 0.22in.

It is available in tape and reel packaging for production requirements. The ZRO2407A1LF is also suitable for automated surface-mount assembly and reflow, as well as fixed-wireless and digital-radio applications that require ultra-low phase-noise performance.

Chip Is Compliant With Bluetooth Low-Energy Spec

Broadcom has announced that its latest-generation Bluetooth combination chip is compliant with the ratified Bluetooth low-energy version of the Bluetooth technology specification. The Bluetooth low-energy specification enables an ultra-low-power implementation of Bluetooth technology, making the technology increasingly applicable for wireless medical and fitness monitoring devices that necessitate long battery life.

With Broadcom's dual-mode implementation, OEMs can extend these new Bluetooth low-energy applications to smartphones and other devices while also enabling an array of existing Bluetooth functions with a single chip.

HRP-75 Power Supply Is Energy Star Compliant

Mean Well has introduced the HRP-75 series, a 75W miniature high-reliability AC/DC enclosed power supply that is now available from Ecopac Power. The HRP-75 series, along with the existing range of products HRPG-150, HRPG-300 and HRPG-600, allows Mean Well to offer various wattage options from 75W to 600W all with PFC function and energy-saving functions.

Featuring low no-load power consumption and an operating efficiency of 89 per cent, the Mean Well HRP-75 series reduces the size and increases the working efficiency in comparison to the existing range of 75W power supplies. With a five-year warranty, the HRP-75 series complies with Energy Star and operates at -30C to +70C. In addition, as the units comply with the 'no load power consumption of less than 0.5W', it allows designers to conform with the requirements of Energy Star and EuP for end-user systems and applications.

The HRP-75 series has a profile of less than 1U (41mm) with overall dimensions of 129mm x 98mm x 38mm. With a universal input of 85-264V AC and built-in active PFC function, the units are designed to withstand 300V AC surge for five seconds and include short-circuit, overload, over-voltage and over-temperature protections. The Mean Well SPV series is supplied with worldwide safety certificates, UL, CUL, TUV, CE and CB.
