It also illustrates how the high 29.5dB maximum gain of the MAX2037 results in improved receiver noise figure.
When high current mode is selected, the IC will perform with maximum gain, IP3 and low noise figure.
In our example, the system gain is very high, thus most spectrum analyzers can accurately measure the noise figure.
Note that the MAX2323 PCS LNA was measured at a 1.9dB noise figure, which could likely be improved further given the time.
Performance is presented for the following areas: Transmit output spectrum, 1dB compression point, S-parameters, noise figure, harmonic output content, gain and supply current.
In order to optimize the performance of a low-noise amplifier, the input- and output-matching circuits must be tuned to tradeoff between noise figure, return loss, and gain.
Extended Noise Figure Data for the MAX2118 Satellite- Maxim Abstract: This application note presents extended noise figure data for the MAX2118 satellite tuner.
The ratio of the signal and the noise is called S/N ratio, and the ratio of S/N of the input and S/N of the output is called NF(noise figure).
The most important parameters that must be taken into consideration when comparing these two solutions include conversion gain, noise figure, and linearity mainly 2nd and 3rd order.
Failure to do this will, for example, cause undesirable emitter degeneration to occur in receive front-end or power-amplifier circuitry, which will result in diminished gain and degraded noise figure performance.
An engineer can measure the noise figure over a certain frequency range, and the analyzer can display the system gain together with the noise figure to help the measurement.
Designed in Maxim's advanced SiGe process, the devices achieve high gain and low noise figure while maximizing the input-referred 1dB compression point and the 3rd-order intercept point.
Assuming that noise figure of the receiver is less than 9dB, as required by the standard, we can deduce from equation 2 the equivalent receiver's 3rd-order intercept point, as dictated by cross-modulation.
Similarly, if the Noise Figure of the DUT is very high(e.g., over 30dB), this method can also be very accurate.
IPG's high power single-mode amplification has very low noise figure, eliminates distortion products and minimizes four-wave-mixing in these DWDM CATV applications.
For a buffer amplifier, a noise figure of 6dB to 7dB has minimal effect on a receiver chain with 1st-stage LNA of 2dB or lower noise figure. .
The MAX2323 is attractive, because the PCS LNA offers two gain steps and excellent 2GHz noise figure, suitable for LEO satellite handset design.
Since the input noise and Signal-to-Noise ratio of the noise source is known to the analyzer, the noise figure of the DUT can be calculated internally and displayed.
We assume that all degradation is due to the phase-noise reciprocal mixing, and the receiver noise figure is less than 9dB as required by the standard.
These losses nibble away at SMPS efficiency since capacitors are used in the power circuit of the SMPS to stabilize voltage and filter both the input and output noise Figure 1.
