General Description
The KSN-2825A-219+ is a Frequency Synthesizer, designed to operate from 3210 to 3310 MHz for internet
wireless application. The KSN-2825A-219+ is packaged in a metal case (size of 0.80" x 0.58" x 0.15") to
shield against unwanted signals and noise. To enhance the robustness of KSN-2825A-219+, each internal
component is secured to the substrate with chip bonder, thereby eliminating the risk of tombstoning during
subsequent solder reflow operations by the customer.
