Question

Which of the following is not a challenge to RF/IF conversion stage in military application?

a.

Low phase noise

b.

Tunable pre-selector

c.

Single RF/IF up-down conversion

d.

Fast tuning synthesizers

Posted under Cognitive Radio

Answer: (c).Single RF/IF up-down conversion Explanation:Tunable pre-selector is required for co-site rejection. Low phase noise and fast tuning synthesizers are required for JTIDS and EPLRS. Single RF/IF up-down conversion is a commercial application challenge.
