ATU Port Expander
he ATU Port Expander is a device that attaches to a Multus Basic or Proficio transceiver’s ATU port, interprets band data sent to it and selects a corresponding output port for the activation of relays (or other devices) such as a low pass filter relay(s). It also provides a separate output port for the activation of a two port remote antenna switch such as the MFJ-4712 (via a bias tee). Each output port is capable of sinking 350ma and has a maximum input voltage of 50V. The ATU Port Expander is well suited for driving inductive loads (relays).

Features:
*Compatible with ATU port of the Basic and Proficio transceivers.
*Six output ports (50V maximum voltage, 350ma per port).
*Separate antenna switch port.
*Port selection configuration via selection jumpers.

The ATU Port Expander is sold as a kit and contains SMT devices. A bare bones option is available that provides the PCB, programmed microprocessor and socket. A bill of material is available on our support forum.

IQBD (IQ Balance Detector)
he IQBD (IQ Balance Detector) is a device to aid in determining the correct volume and phase balance of the IQ audio signal sent to a SDR transceiver. Most transceivers (including the Proficio) that implement Tayloe mixers to generate the transmitted RF signal need at least small adjustments to the volume balance and phase balance of the two channel I/Q audio signal provided to the SDR transceiver. If either volume or phase are unbalanced an image signal is produced in the transmitted RF signal. Determining the strength of the image signal is often performed by listening to the transmitted signal on a second receiver or transceiver. The IQBD eliminates the need for a second receiver or transceiver.

Features:
1) Highly sensitive to IQ out of balance conditions of both volume and phase.
2) LED IQ balance visual indicator.
3) Audio IQ balance output indicator.
4) 5W maximum input power.


The IQBD is sold as a kit and contains SMT devices.

SMSG (S Meter Signal Generator)
The SMSG (S Meter Signal Generator) is device that generates a selectable S9 or S4 signal in one of 4 selectable bands. The SMSG is useful for calibrating the S Meter of any receiver or transceiver. It is particularly useful for calibrating the S Meter of a SDR application such as HDSDR or GSDR and others.

Specifications: Output Impedance: 50
Output Level: S4:1.6uV (-103dBm), S9:50uV (-73dBm)
Amplitude Accuracy: S4: +/- 3dB, S9: +/- 3dB
Output Frequency: 80M (3.686MHz) +/- 30ppm
40M (7.040MHz) +/- 50ppm
30M (10.116MHz) +/- 30ppm
20M (14.070MHz) +/- 30ppm

The SMSG is sold as a kit and contains SMD devices. It is easy to build and will take about 2 hours for an experienced builder.

UIA (USB Isolation Adapter)
The UIA (USB Isolation Adapter) is a USB 2.0 (Full Speed, Low Speed) compliant device that provides complete isolation of a down stream USB device from the up stream host computer. Ground loops are eliminated. Host computer or device generated common mode noise and RF induced noise is significantly reduced or eliminated. It also provides 5000Vrms isolation between the host computer and the down stream device. Also 8KV of ESD protection is provided. The UIA provides these benefits using a number technologies.

1) An Analog Devices ADuM4160™ USB Digital Isolator provides USB isolation.
2) RF chokes are implemented on all voltage supply lines.
3) Separate ground planes have been implemented for both the up stream and down stream.
4) Power for the up stream and down stream devices are completely separated and independent.
5) 8KV ESD protection devices are attached to the USB data lines.

The UIA works with any 2.0 USB Full Speed or Low Speed device. It is the solution for USB connections that suffer with ground loop or noise problems.


The UIA is sold as a kit and contains SMT devices.

MIA (mWattmeter-III Interface Adapter)
The MIA (mWattmeter-III Interface Adapter) provides an interface between the mWattmeter-III and the Proficio transceiver. With this adapter, the transceiver will automatically set the mWattmeter-III to the proper band of operation.
Manually setting the mWattmeter-III band is eliminated.
A firmware update to the mWattmeter-III is required to support the MIA. This is accomplished by replacing the microprocessor in the mWattmeter-III that is included with the MIA kit.

NOTE: If the MIA is being ordered with the mWattmeter-III please select the "No Microprocessor" option below. The mWattmeter-III currently ships with the correct firmware. Also, if you currently own a mWattmeter-III and the firmware revision is 118.040 (or greater), the replacement microprocessor is not needed, select the "No Microprocessor" option below.

The MIA is sold as a kit and contains SMT devices.
