Mini Receiver
FB7-NX
-
In about 1935, the National Radio Company of Malden, Mass., brought out a “hot” high frequency receiver, called the FB7, and the subsequent FB-7X. It featured a super-hetrodyne design with plug-in coils that gave it a broad frequency range. The “X” model also incorporated a crystal filter in the intermediate frequency section, thus giving it additional selectivity. The receiver was viewed by radio amateurs as a technological breakthrough, and it was also used commercially for point to point high frequency communications. As the receiver did not have an internal RF amplifier section, a separately tunable RF amplifier was later provided in a separate enclosure for additional performance capabilities. Now, National RF, Inc., is resurrecting the fabled receiver name with an all solid-state, hot mini receiver, which also utilizes plug-in coils to cover the HF spectrum. The mini-receiver is designed for use by radio amateurs as well as serious short-wave listeners, and allows reception of AM, CW, and SSB signals. It incorporates a super-hetrodyne design with a dual gate FET built-in RF preamplifier and a ceramic filter for selectivity, often required when used in a crowded amateur radio band. In addition, the receiver has a buffered rear panel output of the high frequency oscillator for use with either a frequency counter for exact receive frequency display, or for interface with an outboard transmitter. A rear panel jack is also provided for muting the receiver when a transmitter is placed into the transmit mode. And, the receiver is small enough to fit into carry-on luggage and taken on trips when it is desired to “keep an ear” on amateur radio or other high frequency activity. The receiver utilizes rear panel plug-in coil assemblies which contain the RF amplifier, mixer, and oscillator tuned circuits. Each plug-in coil assembly also comes with a separate dial scale, which is inserted onto the front panel for displaying the tuned frequency. A very smooth 6 to 1 planetary drive is used for tuning the receiver. Other front panel controls include RF preamplifier peak, volume control, Beat Frequency Oscillator adjustment, and RF gain control. Other switches include filter bandwidth, AM/CW/SSB selection, Power, and a general coverage/band spread control for certain plug-in assemblies. The receiver is intended to drive head-phones via a rear panel jack, but has sufficient output to drive a small external speaker.

High Voltage Surge Current Monitors
HVSCM
-
Designed to be used with the Model HVST High Voltage Surge tester. The Surge Current Monitor allows simultaneously surge testing 20 units. The Surge Current Monitor monitors the current going through each unit under test at the time of the surge. If a unit under test breaks down or leaks, the Surge Current Monitor will identify the bad unit by lighting the corresponding LED. The most important features of the surge tester are its ability to test the entire winding insulation system. A high voltage surge generates turn to turn, coil to coil, and phase to phase voltage stress, as well as ground insulation stress. When used as a dielectric test, accurate voltage readings are essential. The HV Surge Tester monitors the voltage directly across the winding under test. In production testing we expect that most of the time the devices will pass. In the event that one should fail, the failed device would be removed and then all the parts would have ot undergo another surge test. Since most devices pass most of the time, simultaneous surge testing can be a real time saver.

Round Wire Coil Inductors
-
Round wire coil (RWC) inductors come in six platform sizes and enable the highest efficiency of any SMT inductor through the use of a low loss ferrite core material which minimizes AC losses and also eliminates thermal ageing. The use of round magnetic wire instead of rectangular flat coils enables a lower cost while still maintaining a low DCR and small footprint. The platforms have passed the AEC-Q200 stress test qualification proving the designs robustness and suitability to difficult environments but the parts are not IATF certified. The platform range from 7.6×7.4×6.4mm to 26x26x15mm and are suitable for a wide range of applications and markets including communications, computing and industrial.

Rotational Flow Demonstration Kit
-
The rotational flow demonstration kit detects the rotational position using the MCU’s on board data transfer controller (DTC) function, a form of state machine, while the MCU’s core is in stop-mode state. This ensures that the average power consumption is kept as low as possible, with IAV (average current) at 4.5 microampere (μA) and a 32 sample burst per second. The flow demonstration kit senses the flow direction and volumetric flow rate of water and gas, and can also detect reverse flow. The demonstration kit is applied using an active inductive method. Two coils are used to sense the rotational position of a part-metalized disk, and a third coil is used to generate a reference signal.
