Figure 3. Adding an external LNA(the MAX2640) increases receiver sensitivity, but lowers the third-order intercept point.
All devices are designed to have best receiver sensitivity at lowest current consumption offering an additional power down feature to further save battery life.
SINAD is usually expressed in dB and is quoted alongside the receiver RF sensitivity, to give a quantitative evaluation of the receiver sensitivity.
Reciprocal mixing of strong RF signals with the LO noise degrades the receiver sensitivity.
Based on typical baseband processing gain and desired BER after demodulation, this receiver sensitivity corresponds to a 9dB maximum receiver NF.
For example, average implementations of the Bluetooth LE 125K(Coded) PHY are achieving a receiver sensitivity of -103 dBm.
This technical paper provides a step-by-step development of the receiver sensitivity equation and concludes with numeric example, putting its mathematical definition to the test.
Receiver sensitivity is also dependent on LO phase noise, but it also does not place a stringent phase-noise requirement on the radio, even in the case of 16QAM modulation.
Receiver Sensitivity Equation for Spread Spectrum Sy- Maxim Abstract: The following application note provides insight into how the sensitivity of a spread spectrum application is defined and how the desired sensitivity level for digital communication receivers can be calculated.
For BTS applications, the ADC often does not have sufficient dynamic range to meet both the noise figure requirements(receiver sensitivity) and maximum blocker requirements without implementing automatic gain control AGC.
Once the transmitted power and the receiver sensitivity are established, the path loss of the signal from transmitter to receiver is the main determination of usable range.
Receiver sensitivity is compliant with power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to specified value applied through the recommended power supply filtering network.
Receiver sensitivity is'-105dBm(at 100kbps), the best in the industry, and it can even be improved by using the built-in error correction function FEC *4.
One way to enhance receiver sensitivity is to add an external low-noise amplifier(Figure 3), but the restriction in dynamic range associated with that approach may be unacceptable in your application.
The AP generally has better receiver sensitivity and diversity support than the phone, so it should be able to receive the slightly lower strength phone signal.
Given that the system's receiver sensitivity is fixed at -70dBm, the practical solution to increasing range was to increase the radio transmit power.
Defining Dynamic Range Receiver sensitivity is one component of the system's dynamic range-sensitivity defines the minimum signal level that allows the receiver to successfully recover the transmitted information.
It is packaged in a rugged, compact housing, providing an effective way of testing the transmission capability and receiver sensitivity of network equipment, particularly for telecom and datacom requirements.
The MAX1470, MAX1471, and MAX1473 receivers offer their best receiver sensitivity while drawing 5mA from a supply voltage of only 3.3V.
Introduction The communication standards for wireless base stations-e. g., GSM, UMTS, and(now) LTE-define minimum specifications for various parameters including receiver sensitivity and performance in the presence of large signals.
