Not too long ago, cardiac monitors were purely local — meaning that their beeps, alarms and data were available only to medical personnel in physical proximity to the monitors. The introduction of telemetry meant that those alarms and patient data (such as pulse rates, blood pressure and other vital data) could be transmitted from patient hospital rooms to a nursing station or another centralized monitoring location. For years all data had traveled over wires, limiting access to specific care settings within a medical facility.
Today, thanks to advances in wireless infrastructure technology, those same alarms and cardiac stats can be transmitted to doctors from ambulatory patients. Wireless telemetry systems can now connect a central station and hundreds of transceivers or wireless bedside monitors — communicating vital signs and integrating real-time monitoring with lab results and radiology images, to make sure doctors have the patient's information at all times.
A Denmark-based industrial R&D firm, RTX A/S, worked with Qorvo supplier Richardson RFPD to qualify one of Qorvo's power amplifiers into a multibillion-dollar health care company's wireless telemetry system. Qorvo's power amplifier supports the high data rates needed for this long-range application, offering outstanding power-added efficiency for longer battery life and ensuring uninterrupted cardiac monitoring. The device was designed on Qorvo's advanced InGaP HBT GaAs technology to deliver superior reliability, temperature stability and ruggedness.
