EM Research – High-performance frequency synthesiser and crystal oscillators launched (THOR-14000-XA)Aug 31 2012 - Design & Manufacture [More Design & Manufacture Articles]
EM Research has introduced three new products – the THOR-14000-XA frequency synthesizer, the PLXO-100-XA phase-locked crystal oscillator and the CLX-1020-XA phase-locked oscillator
1 – The THOR-14000-XA frequency synthesizer is designed to operate from 13.6 to 14GHz in 1MHz steps and features fast switching of ≤400µSec band-edge to band-edge, and ≤300µSec channel to channel. Locked to an external 10MHz reference, the device exhibits low phase noise (<-86dBc/Hz at 10KHz) and low current draw (+5VDC at 335mA).
The THOR units are capable of maintaining ‘excellent’ performance over vibration, shock and temperature featuring a rugged, module-mount package (2.50 x 1.1 x 0.4 inches), which can be optionally hermetically-sealed and contains removable SMA connectors for surface-mountability. The THOR-14000 units also feature low sub-harmonics (-25dBc), low spurs (<-65dBc) and a wide operating temperature range (-40C to +85C).
2 – The PLXO-100-XA is a phase-locked crystal oscillator operating at 100MHz and features an internal reference-detect switch. When no reference is connected to the device, the reference detect switch automatically engages a 10MHz internal TCXO, providing uninterrupted use of the PLXO-100. Otherwise, the device Locks to an external 10MHz frequency reference and exhibits exceptionally-low phase noise (-142dBc/Hz at 1 KHz offset), low spurs (-70dBc), 0dBm output power on a supply voltage of +12VDC.
3 – The CLX-1020-XA phase-locked oscillator that operates at 1020MHz and features exceptionally-low phase noise (<-109dBc/Hz at 10KHz). The unit is locked to an internal reference and offers +7dBm output power with low power consumption (+5VDC at <65mA) and low spurs (<-80dBc).
With its exceptional low phase noise characteristics, the CLX is ideal for transmitter sources and local oscillators in avionics, radio astronomy and communications, telemetry, ISM-Band applications, and in cellular, WiMAX and LTE base stations, says the company.More news from EM Research
