Monolithic microwave integrated circuit, or MMIC (sometimes pronounced "mimic"), is a type of integrated circuit (IC) device that operates at microwave frequencies (300 MHz to 300 GHz). These devices typically perform functions such as microwave mixing , power amplification, low-noise amplification , and high-frequency switching.
Like other electrical switches, RF and microwave switches provide different configurations for many different applications. Below is a list of typical switch configurations and usage: Single pole, double throw (SPDT or 1:2) switches route signals from one input to two output paths. Single pole double throw (SPDT) switch from Agilent Technologies
SMA connectors must not be confused with the standard household 75-ohm type F coax connector (diameters: male 7 ⁄ 16 inch (11 mm) circular or hex; female 3 ⁄ 8 inch (9.5 mm) external threads), as there is only about a 2 mm difference overall in the specifications. Type F cannot be mated with SMA connectors without the use of an adapter.
LTspice is a SPICE-based analog electronic circuit simulator computer software, produced by semiconductor manufacturer Analog Devices (originally by Linear Technology). [2] It is the most widely distributed and used SPICE software in the industry. [6]
The N connector follows MIL-STD-348, a standard defined by the US military, and comes in 50 and 75 ohm versions. The 50 ohm version is widely used in the infrastructure of land mobile, wireless data, paging and cellular systems. The 75 ohm version is primarily used in the infrastructure of cable television systems. Connecting these two ...
Compact Software was the first commercially successful [citation needed] microwave computer-aided design (CAD) company. The company was founded in 1973 by Les Besser [1] [2] [3] to commercialize his eponymous program COMPACT (Computerized Optimization of Microwave Passive and Active CircuiTs), released when he was at Farinon Electric Company.
These have inaccurate absolute timing (more than 100 parts per million) that is yet very repeatable (often less than 1 ppm). Software can do the math to make these into accurate RTCs. The hardware timer can produce a periodic interrupt, e.g. 50 Hz, to mimic a historic RTC (see below). However, it uses math to adjust the timing chain for accuracy:
The generator may have additional sections to modify the basic signal. The 8088 for example, used a 2/3 duty cycle clock, which required the clock generator to incorporate logic to convert the 50/50 duty cycle which is typical of raw oscillators. Other such optional sections include frequency divider or clock multiplier sections. Programmable ...
