Product Overview

Mini-Circuits’ USB-2SP4T-63H is a low cost, USB controlled, solid state matrix, containing two independent SP4T RF switches. Each
fast switching, absorptive switch operates from 10 MHz to 6000 MHz with 5 µs typical switch transition speed. High linearity (+50 dBm
typ IP3), and high isolation (85 dB typical) allow the model to be used for a wide variety of RF applications.

Full software support is provided for USB control, including our user-friendly GUI application for Windows and a full API with
programming instructions for Windows and Linux environments (both 32-bit and 64-bit systems). The latest version of the full software
package can be downloaded from https://www.minicircuits.com/softwaredownload/solidstate.html at any time.

The USB-2SP4T-63H is housed in a compact, low prole, rugged metal case (8.4” x 2.00” x 0.475”) with 10 SMA (F) connectors

(COM, 1 to 4 for each switch), a USB Mini-B port for power and control, and two data bus connectors for Master / Slave connections
to other modules.

In disconnected state COM port is reflective and ports 1-4 are absorptive, isolation COM to 1,2,4 is significantly better than COM to 3. See block diagram on page

3 for details.

2

IP3 is tested with 1 MHz span between signals, +5 dBm per tone.

3

Transition time spec represents the time that the RF signal paths are interrupted during switching and thus is specified without communication delays.

4

Minimum dwell time is the shortest time that can be achieved between 2 switch transitions when programming an automated switch sequence.

5

Switching time(USB) is the time from issuing a single software command via USB to the switch state changing. The most significant factor is the host PC, influenced

by CPU load and USB protocol. The time shown is an estimate for a medium CPU load and USB 2.0 connection.

6

Current consumption specied for a single unit without any slave modules.

7

Pass through current is the maximum current handling of a unit with slave modules attached. If controlling a large number of slave modules additional power supplies

should be included to ensure this limit is not exceeded. See page 4 for details.

USB-2SP4T-63H

Connecting multiple modules (Daisy Chain)

The USB-2SP4T-63H is designed to connect up to 35 modules in series (Daisy chain) using dynamic addressing, meaning there is no

need to specically set the address of the modules, the addresses will be set automatically as part of establishing the communications
with the PC. The module connected to the PC USB port will be assigned address 0 (Master), the rst module connected to it will get

address 1(slave) and subsequent modules incrementing up to address 34 (slave).

Connections between modules will be made using the serial in/out ports with the module connected to the PC as a master and all
others as slave modules. All control will be through the master module (address zero) which is the only one communicating with the
PC. Serial control out port of each module should be connected to the serial control in port of the next module. Power will be supplied
from the PC via the master module up to a maximum of 500mA.

If connecting USB-2SP4T-63H units in series, additional power supply will generally be needed every six to eight modules. If mixing
modules of different types ensure the max current through any unit does not exceed 500mA. All power supplies should be connected
to the module via the module’s USB port, connecting an additional power supply will automatically cut off power draw from the serial
control in port for that module.

The Serial master/slave bus allows connecting modules of different types to the same daisy chain as long as all support Mini-Circuits
Dynamic addressing setup. To add a new module to the set up simply connect the module to the setup and refresh the address listing,
no need to reset any of the existing modules or assign addresses manually.

Connecting slave units should be done only with control cables provided by Mini-Circuits
