What is the name of a device that combines several semiconductors and other components into one package?
The correct answer is Integrated circuit (IC). An integrated circuit is a device that combines several semiconductors and other components into one package. ICs contain multiple transistors, diodes, resistors, and capacitors fabricated on a single silicon chip, creating complex circuits in a small package. For amateur radio operators, ICs are found throughout modern equipment - in microprocessors, operational amplifiers, voltage regulators, RF chips, and digital logic circuits. ICs revolutionized electronics by making complex circuits small, reliable, and affordable. Understanding ICs helps when working with modern radio equipment, as most functions are now implemented using integrated circuits rather than discrete components.
Exam Tip
Integrated circuit = combines multiple components in one package. Think 'I'C = 'I'ntegrated 'C'omponents in one chip. Transducers convert energy, relays switch, transformers transform - none combine multiple semiconductors into one package.
Memory Aid
"Integrated circuit = combines components in one package. Think 'I'C = 'I'ntegrated 'C'omponents. Multiple semiconductors and parts in a single chip package."
Real-World Application
Your transceiver's audio amplifier might use an integrated circuit that contains dozens of transistors, resistors, and capacitors all on one tiny chip. This IC replaces what would have been a large circuit board full of discrete components. The IC is more reliable, smaller, and cheaper than building the same circuit with individual parts. Modern radios are full of ICs performing various functions.
Key Concepts
Why Other Options Are Wrong
Option A (Transducer): Incorrect. A transducer converts one form of energy to another (like sound to electrical). It's a single device, not a package combining multiple semiconductors and components.
Option B (Multi-pole relay): Incorrect. A relay is an electromagnetic switch with multiple contacts. While it has multiple poles, it doesn't combine semiconductors and other components - it's just a switch mechanism.
Option D (Transformer): Incorrect. A transformer has multiple windings but doesn't combine semiconductors. It's an electromagnetic device for voltage transformation, not an integrated circuit.
