The mixer circuit can be used not only to shift the frequency of an input signal as in a receiver, but also as a product detector, modulator, phase detector or frequency multiplier. [6] For example, a communications receiver might contain two mixer stages for conversion of the input signal to an intermediate frequency and another mixer employed ...
A mixer-based detector (e.g., a Schottky diode-based double-balanced mixer) provides "the ultimate in phase noise floor performance" and "in system sensitivity." since it does not create finite pulse widths at the phase detector output. [2] Another advantage of a mixer-based PD is its relative simplicity. [2]
Diodes Incorporated is a global manufacturer and supplier of application specific standard products within the discrete, logic, analog, and mixed-signal semiconductor markets. Diodes serves the consumer electronics, computing, communications, industrial, and automotive markets.
Diode mixers take advantage of the non-linearity of diode devices to produce the desired multiplication in the squared term. They are very inefficient as most of the power output is in other unwanted terms which need filtering out. Inexpensive AM radios still use diode mixers. Electronic mixers are usually made with transistors and/or diodes ...
The 1N4148 is a standard silicon switching signal diode. It is one of the most popular and long-lived switching diodes because of its dependable specifications and low cost. Its name follows the JEDEC nomenclature. The 1N4148 is useful in switching applications up to about 100 MHz with a reverse-recovery time of no more than 4 ns.
MiniMelf diode. Metal electrode leadless face (MELF) is a type of leadless cylindrical electronic surface mount device package with metal end terminals. Diodes and resistors are the most common MELF devices. [1] The EN 140401-803 and JEDEC DO-213 standards describe multiple MELF components. [2]
IQ imbalance is a performance-limiting issue in the design of a class of radio receivers known as direct conversion receivers. [ a ] These translate the received radio frequency (RF, or pass-band ) signal directly from the carrier frequency f c {\displaystyle f_{c}} to baseband using a single mixing stage.
The DO-35 (also known as DO-204-AH or SOD27) is a semiconductor package used to encapsulate signal diodes (i.e., diodes meant to handle small amounts of current and voltage). [ 10 ] [ 13 ] [ 2 ] It is often used to package small signal, low power diodes such as 1N4148 (a 100 V, 300 mA silicon diode.)
