Table 3.1. Antenna Efficiency and Peak Gain
Parameter With optimal layout Note
Efficiency -1 dB Antenna efficiency, gain and radiation pattern are highly depend-
ent on the application PCB layout and mechanical design. Refer
to Design Guidelines for recommendations to achieve optimal an-
tenna performance.
Peak gain 1.86 dBi
3.4 Power Supply
The MGM220P requires a single nominal supply level of 3.0 V to operate. All necessary decoupling and filtering components are inclu-
ded in the module.
