Qorvo's QPF4219 FEM, available from Mouser Electronics, integrates a 2.4 GHz power amplifier (PA), regulator, single-pole double-throw (SPDT) switch, low noise amplifier (LNA) with bypass mode, and voltage power detector
into a single device.
The switches are controlled by the RF front-end where a power detector
continuously samples the signal and when the sampled signal exceeds the threshold the switches are turned on for array mode.
Similarly, the RFX2502 comes integrated with a high-efficiency, higher saturated and linear power output power amplifier (PA), low noise amplifier (LNA), Transmit/Receive switch, and directional power detector
The SynthNV programmable 34.4-MHz to 4.4-GHz software-tunable RF signal and sweep generator includes a built-in RF power detector
. It is controlled and powered from any device running Windows, Linux, or Android OS via a USB port.
SKY85405 is a high power 802.11ac WLAN power amplifier with integrated power detector
offering superior output power, linearity, and efficiency.
In this work, a cross-layer solution, based on the combined use of a duty-cycling protocol  and a new kind of active wake-up circuit, based on a very-low-consumption radio frequency (RF) power detector
never adopted in the literature so far, is presented and validated.
Let [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] be the phasor representation of the original transmitted signal reached at the receiver antenna and let [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] be the phasor representation of local oscillator (LO) signal; then the power [P.sub.k] detected by the kth power detector
can be written as in
Power Secure's first line of defense against this issue is a low power detector
on the SSD.
In regard to an ideal photo power detector
, S should be kept with a constant quantity to maintain the linear relationship between sensing power and sensor output voltage as follows.
Fujitsu Laboratories has developed a diode-based power detector
with a technology that simultaneously enables temperature compensation, resulting in a power detector
with a mounted area of only 0.04 mm2 and power consumption of 0.3 mW.
To this purpose a study of the mm-wave emission of the Sun (also in the presence of a flare) has been combined with a transistor-level modeling of the main radiometer building blocks (power detector
The HMC992LP5E combines a high performance analog voltage variable attenu ator (VVA) core with a high speed power detector
in a 5 mm x 5 mm plastic package to offer a complete, compact automatic gain controller (IF-AGC) solution.
