Testing is a cost-avoidance activity. The production test costs for cellular mobile phones can represent a high percentage of the item cost. Deciding the appropriate depth of test for parametric and ...

Abstract: This paper presents a cross-covariance-based time- delay estimation method for accurate determination of the time- delay between the input and the output of a RF power amplifier/transmitter.

A mobile phone undergoes five principal operations: firmware installation, alignment, RF characterization, assembly, and functional test. PXI instruments are emerging that can perform the alignment ...

while start_coord_adj <= rf_seq_len - (start_coord - end_coord + 1): rf_subseg_0dot = rf_seq[start_coord_adj - 1:].replace('.', '') start_coord_adj_found = rf_subseg ...

Abstract: In the rapidly evolving field of radio frequency (RF) engineering, precise antenna alignment remains a critical challenge, directly influencing communication performance and reliability.

SAMTEC RF edge launch connectors are designed with a narrow body design that is 33% smaller than traditional edge launch connectors. Devices are commonly used in a lab setting for high-frequency test ...
