The RF Enclosure MINI-EXT-FX is a new line of RF enclosures that speed up your RF development project by creating housing, high-performance SMA ports, RF grounding, and thermal stability all in one go. Best of all, replacing the PCB with a new revision is easy, so the enclosure can be reused for your next project.
The RF MINI-EXT-FX can be conveniently used in small-series production.
The EXT designation refers to the doubled length of the PCB that fits in the enclosure, compared to the MINI version. The [...]

One of the most common reasons to use an RF enclosure from the Gquipment Mini series is to house some RF/microwave PCB to create an RF module with some specific function. To evaluate the design criteria of this function, one must measure the RF module—for example, by measuring its S-parameters with a VNA using the RF ports of the RF Enclosure Mini. Then, the RF PCB is the DUT, and the RF Enclosure Mini is used as a test fixture.
Of course, the influence of the RF ports should be minimal; however, in practi [...]

1. Introduction
Return loss is an important parameters of any RF (Radio Frequency) device. It is a measure of the amount of power reflected at a port. From it, impedance levels can be calculated and amplitude variations in transmission lines predicted. For one port devices, it is the only existing scattering parameter too!
Usually, return loss is measured using a directional coupl [...]
