The “CORE Low Power RF Switching Module”
is the central and easily the most essential
component for optimizing Production Line
Cycle Time, specifically as regards any low
power RF ATE station design.
The realization of the best possible scenario
for multiport testing is achieved by reducing
not only the test time, but by also drastically
reducing the number of required test
technician interactions and thus lowering
the overall amount of DUT handling.
This module is expandable, using multiple
modules, to a surprisingly high number of
test ports with a very acceptable “bypass
loss” of .6 dB to 1.1 dB for each added
module, across the entire cellular test band.
Application Features
• 6 DUT Test Ports
• 2 pair Test Equip Ports
• 2 Module Bypass Ports
• ‘Universal’ Module Control
Module Supports up to two pieces of
“2-port” low power RF test equipment.
“Test Equip Ports” are selectable by
pair and each port is fully multiplexed
to all of the DUT Test Ports.
“Module Bypass Ports” are dedicated to
the active pair of Test Equip Ports and
are selected similar to a DUT Test Port.
Non-associated to any DUT Test Ports.
“DUT Test Ports” are well isolated and
are terminated very close to the front
panel RF connection.
“Universal Module Control” through a
“no firmware, generic control hardware”
design rule for all Xplatform modules.
• site commonality
• equip cost savings
• future proof design
• good performance
Supported Options (per hardware design):
• RF Switches: Multiple Drive Types / Vendors
• Module Control*: TTL or TTL with I2C or only I2C
• Switch Cycle Counter**
* Note: “Stand-Alone” Module USB control is within design capabilities
** Note: “Switch Cycle Counter” option availability to be announced
