4.1 Unidirectional Receiver Application

A receiver application that operates in several frequency bands can be realized in multiple ways. The following are the applicable scenarios:
  • Low band and high band with two antennas
  • Low band and high band with one antenna
  • Same frequency band with two antennas
  • Same frequency band with one antenna

From an application and performance standpoint, the recommendation is the first approach, as it allows optimal matching and minimizes system losses. If a two-antenna approach is not feasible, the recommendation is to use the built-in SPDT switch to achieve suitable isolation and optimized performance.
