Single conversion VHF/UHF receiver design and the impact of monolithic technology

Single conversion VHF/UHF receiver design have become popular in the last several years. With the advent of monolithic crystal filters and monolithic IC´s, single conversion receivers can now be Justified on the basis of cost, as well as the performance improvements that result. The design of a single conversion receiver presents the designer with a far more difficult challenge than traditional double conversion designs. The fundamental receiver design rules still apply, as always. However, the attention to details is far more important to achieve success.
