EM-based Componen and Circuit Design Software

This version 6.2 of LINMIC is a microwave/ RF IC design suite that has revised the active device modeling for ease of use and for parameter extraction including detailed control of model quality. Aside of lumped device modeling, now MESFETs/HEMTs/MOSFETs can also be modeled as geometric/distributed entities. These distributed transistor models can then also be used for harmonic balance simulation and, in addition to standard results like power levels and dynamic loadlines, the voltages and currents along the transistor fingers can be visualized. For the simulation of nonlinear circuits with complex input signals, envelope simulation has been added and many specific improvements and amendments suggested by users have been implemented. All GUIs have been revised for further improving the ease and convenience of use.

The CRO3120A is primarily used in the point-to-point wireless radio industry and is designed for harsh environments and can withstand temperature fluctuations from –55° to +85°C. Size: 0.5" x 0.5" x 0.22". Price: $29.95.

L-band Matrix

The model 13853 is a 16 x 16 non-blocking matrix. This matrix can be used to connect up to sixteen LNBs to up to sixteen satellite receivers in any combination through rear panel F type connectors, while supplying a DC feed to the amplifiers. The non-blocking feature allows multiple receivers to connect to one LNB. The system can also combine multiple inputs into one output. The unit mounts in a standard 19" equipment rack. Chassis slides are provided for mounting. This unit operates at 950 to 1750 MHz, offers unity gain, RS-232 interface remote control, crosspoint verification and front panel keypad control with LCD display. Size: 19" x 5.25" x 25.00". Delivery: 12 weeks.

Switch Modules

This SVM family of VME-based switches address power, DC signal and RF applications. These high density switches are available in solid-state and electromechanical designs and support VME32/64 operation. Key features include: scan list operation, programmable delays, interrupt driven triggering and internal confidence checking. Additionally, the safety interrupt is a programmable fail-safe feature permitting all relays to be opened based upon a user defined event. These intelligent switching features are achieved in hardware, rather than through driver or on-board firmware, thereby greatly increasing system throughput and reducing software programming overhead.
