Reducing the overall size and lowering the total bill of materials (BOM) has been the primary objective in the design of the MICRF505. Through high integration the number of external components has been reduced to just a handful of capacitors, one inductor and a crystal. The MICRF505 is designed to accommodate low cost, low accuracy crystals. To address this, Micrel added a frequency error estimator to determine frequency mismatch between communicating transceivers, and an internal crystal tuning mechanism to enable automated crystal tuning on-the-fly. The MICRF505 also incorporates an internal clock recovery circuit to reduce the burden on its companion baseband device enabling the use of a lower cost micro-controller.

The MICRF505 features high sensitivity, selectivity and transmit power so RF performance has not been sacrificed in the process of driving down BOM cost. In fact by integrating the transmit/receive (T/R) switch there are no switch losses, making the system level RF performance even higher.
