VECTOR-RECEIVER LOAD PULL MEASUREMENTS
A modern and efficient methodology for load pull measurements. Low-loss couplers are placed between the tuners and device-under-test and are connected to a vector receiver such as a VNA. Doing so allows the a- and b-waves to be measured at the DUT reference plane in real-time, presenting vector information not normally made available.
ACTIVE / HYBRID LOAD PULL
Active Load Pull
Active load pull relies on external sources to inject a signal into the output of the DUT, thereby creating a2. Because a2 is no longer limited to a fraction of the original reflected signal, as is the case with the traditional passive mechanical tuner, external amplifiers may be used to increase a2 nearly indefinitely so that ΓL can achieve unity.
Hybrid Passive-Active Load Pull
Hybrid load pull refers to a combination of active and passive tuning in the same system. It is a technique designed to obtain the advantages of both active and passive systems while minimizing the disadvantages.
NOISE FIGURE / NOISE PARAMETER MEASUREMENTS
Introduction
Noise occurs naturally in any active device or circuit, and limits the minimum levels of useful signals. Therefore, it is important to design circuits to minimize the effects of noise. To do this, the noise must be quantified and measured in the form of noise parameters.
Ultra-Fast Noise Parameters
A new ultra-fast noise parameter measurement method is able to improve overall calibration and measurement time by a factor of 100X-400X, bringing measurements that could once take tens or hundreds of hours to tens of minutes.
PULSED-BIAS PULSED-RF HARMONIC LOAD PULL
Pulsed Measurements
Because GaN devices tend to self-heat and are susceptible to trapping effects, it is important to pulse voltages between a quiescent and hot value and define appropriate pulse-widths. Pulsing the voltage will result in a lower average power being delivered to the device and reduced self-heating.
Pulsed Load Pull
Load pull consists of varying or "pulling" the load impedance seen by a device-under-test (DUT) while measuring its performance under actual operating conditions. This method is important for large signal, nonlinear devices where the operating parameters may change with power level or impedance. Because the device will operate differently under DC and pulsed- bias conditions, a difference in load pull contours is expected.
