2] problems of a direct-conversion receiver
[8,9], a low-IF receiver is also widely chosen and implemented [10-13].
A series of tests is designed to identify the limiting stage in a fully integrated direct-conversion receiver
An example of an UTRA/FDD direct-conversion receiver
is shown in Figure 6.
With the tremendous advances in RFIC technology, over the last few years, direct-conversion receiver
ICs are fast becoming popular with pager designers.
Obviously, direct-conversion receivers
require no expensive and bulky external filter for analog channel selectivity.

Good mixer balancing is also important in a receiving mixer to suppress LO noise, especially at very low intermediate frequencies or in direct-conversion receivers
