Rf Module For Indoor Unit

EE JULY/AUGUST 1987 by R v Terborgh The series of articles on satellite TV reception, started in the September 1986 issue of Elektor Electronics, has met a great deal of interest from our readers. Many have success- fully ventured out into the world of centimetre waves and SHF construction methods, and are proud to watch the pictures pro- duced by a home-made Indoor Unit (1). The construction and alignment of the RF input stage and the local oscillators is undoubtedly the most difficult phase of the project. However, an attractive alternative is now available for those constructors hesitant about their skills in dealing with very high frequency compo- nents and techniques. The Type HL ECS51 is a ready-made, tunable, 950-1750 MHz to 480 MHz converter of Taiwan- ese origin, and is eminently suitable for taking over the previously mentioned functions on the RF board (Type EPS 86082-1). The module is tuned with a voltage between 0 and 20 V, and requires no band (H/L) switch. It has a ...
