Functional Description
The SKY42068 consists of a high dynamic active mixer, LO
amplifiers, and a selectable LO input. The SKY42068 was
specifically designed to meet the needs of high performance
receivers.
The mixer shares two independent LO signals, LO_1 and LO_2,
that are selected using a common CMOS-compatible control
signal. With this ability, the device can be used in applications
where frequency hopping is required.
Electrical and Mechanical Specifications
Signal pin assignments and functional pin descriptions are
described in Table 1. The absolute maximum ratings of the
SKY42068 are provided in Table 2. The recommended operating
conditions are specified in Table 3 and electrical specifications
are provided in Table 4.
