Qorvo
Cascade Calculator
RF Designers often require several parameter details when placing several amplifiers in a chain. This Qorvo Cascade Calculator provides performance values for system level gain, noise figure (NF) and P1dB for up to 3 cascaded power amplifiers in a chain. NF is the measure of an amplifier's contribution to the overall noise in the system. It is the ratio of the signal-to-noise ratio at the input of the amplifier to the signal-to-noise ratio at the output of the amplifier. P1dB or output power at 1 dB compression point, is the output power level at which the actual gain deviates from the small signal gain by 1 dB.
Noise Figure and Noise Temperature Calculator
Noise figure and noise temperature are used interchangeably. NF measures degradation of the signal-to-noise ratio (SNR), which is caused due to RF and electronic components used in the transmit or receive chain. The noise figure number is displayed in decibels (dB), and represents the performance by which an amplifier or RF receiver can be measured. Noise temperature is the noise power of a component that is introduced into a system. The noise temperature is directly proportional to the temperature in degrees Kelvin.

Cascade Analysis Calculator
Qorvo
Cascade Analysis Calculator let's you go easily from datasheet to analysis. Designed to analyze up to 10 stages, this calculator offers a simple yet powerful way to analyze multi-component systems for their cascaded gain, noise figure, compression point and linearity. Various online cascade analysis calculators have one built-in problem: all stages must be specified with either input or output power parameters. Unfortunately, component datasheets are hardly universal in this regard—most active components such as amplifiers are specified in terms of output power and output IP3, but passive components such as mixers and attenuators are often specified by their input values.
This variation in specifications used to mean that a microwave system designer had to convert between input and output specifications (or vice-versa) in order to use a cascade analysis tool. While this conversion is simple for most parameters, converting output P1 dB to its input equivalent often leads to the following question: "Do I add '1' or subtract '1' to the gain to determine the input P1 dB?" This calculator lets one choose between input or output specifications for each component in a line-up—and go straight from datasheet to analysis without any questions.
