According to one example configuration, an apparatus enhances functionality of a mobile communication device. The apparatus includes an encasement in which to retain the mobile communication device and supplemental circuitry. The supplemental circuitry is operable to: i) control an optical transmitter in the supplemental circuitry to irradiate matter under test, ii) monitor attributes of an optical signal reflected off the matter under test and received by the optical receiver; and iii) communicate the attributes of the optical signal from the supplemental circuitry to the mobile communication device over a communication link. The supplemental circuitry optionally includes multiple electrodes to further monitor attributes of the matter under test.

Apparatus and methods are disclosed related to radio frequency (RF) power detection. One such apparatus includes a directional coupler, an RF switch, and an RF power detector. The RF switch can selectively change coupling between the directional coupler and the RF power detector. This can enable accurate power detection based on a ratio of power levels, without factory calibration or laser trimming.
