TELEDYNE DEFENCE LIMITED HF Synchronous Channelisers LM070 LM071 A Teledyne Technologies Company Features 1MHz to 10MHz 7MHz to 15MHz OPTIONS : DC to 10MHz (LMO68) 10 MHz to 30 MHz (LMO69) LOW LOSS (< 11dB) Small Form Factor Applications COMINT Receiver Pre-selection HF Digital Receivers Product Description The LM071 channeliser covers the HF band of 1MHz to 10MHz in 1MHz channels. The LM070 channeliser covers the HF band of 7MHz to 15MHz, each channel being 1 MHz wide. Both products can be combined to provide full 1MHz to 15MHz HF coverage from two antenas. Unlike traditional approaches utilizing a high degree power divider followed by individual filters, TDL’s innovative approach presents a compact, direct, channelised solution combining a number of filters to a single antenna feed using it’s expertise in filtering to offer a smaller and more power efficient solution without compromising on signal fidelity. The LM070 and LM071 utilise proprietary Teledyne Defence technology to provide state of the art performance in a compact size, weight and power package. Different channel combinations are easily scaleable to cover the full HF band of DC to 30MHz. For further information on the LM068 - LM071 range of products, please contact the Sales Department or your Key Accounts Representative.

The solution proposed effectively splits a common input into a number of separate channels and by TDL proprietary filtering techniques absorbs the power splitting network into the filter structure giving a lower overall noise figure and thus greater sensitivity.
