Silicon Labs announces the launch of Si4830 AM / FM receiver chip Silicon Laboratories, a leading manufacturer of high-performance analog and mixed-signal ICs, announced the launch of the Si4830 AM / FM receiver chip, thereby bringing the benefits of digital performance and integration to mechanically tuned analog radios. Silicon Labs' new Si4830 AM / FM receiver chip reduces product design time and system cost, and improves the manufacturing efficiency of many types of radio products, such as portable radios, stereo radios, clock and desk lamp radios, toy radios and gift radios . The Si4830 is the industry's first AM / FM radio chip with CMOS technology and provides complete AM / FM radio functions in a single chip, including from antenna input to audio output. The high level of integration makes it require more than 80% fewer components than existing solutions. Using Si4830 eliminates the need for external microcontrollers, AM / FM filters, tuning inductors and other components, significantly reducing bill of materials and labor costs. Developers only need to add antennas, mechanical tuning and volume control rollers, amplifiers and two AAA batteries. Yes, the Si4830 receiver chip has become a low-cost radio design platform. The Si4830 AM / FM receiver chip is designed for global radio manufacturers, especially manufacturers in China. At present, China is still a world manufacturing center that uses traditional analog technology to design AM / FM radios. 100 million units. These analog technology-intensive radio designs usually require dozens of discrete components and require extensive reprocessing and manual adjustment during manufacturing and assembly. The Si4830 requires only 12 surface-mount components and only requires 20mm2 of single-sided circuit board area. This exquisite design and convenient board configuration further reduce the cost and extend the AM / FM function to more end products. "Many mechanically tuned AM / FM radio manufacturers have no alternatives and have to construct and manufacture low-cost radios in a labor-intensive, discrete manner," said Dave Bresemann, vice president of broadcast products at Silicon Labs, "our mixed signal receiver The chip Si4830 applies advanced digital broadcasting technology to the analog and mechanically tuned radio market, and creates new business opportunities for customers by reducing production costs and adding AM / FM broadcasting functions to a variety of consumer electronics products. " The Si4830 complies with the European EN55020 standard and provides easy, accurate, and reliable tuning for the global FM band 64-108MHz and AM band 520-1710kHz. Price and Availability The Si4830 AM / FM receiver chip is available now. With a purchase price of 10,000 pieces, the unit price starts at $ 2.10 and comes in a 24-pin SSOP package. The Si4830-DEMO demonstration kit designed to speed up product evaluation and development is now available, and the recommended price is $ 50. An Indoor Access Point is a device for wireless local area networks (WLAN) that provides wireless network coverage and connectivity. It can connect to a wired network and transmit data via a wireless signal, allowing users to connect to the network wirelessly within coverage.

Indoor access points come in a variety of different types and specifications to suit different scenarios and needs. Here are some common types of indoor access points:
1. Single Band Access Point: A single band access point operates in the 2.4GHz band and typically provides a maximum transfer rate of 300Mbps. This type of access point is suitable for small office or home networks because the 2.4GHz band has better penetration and coverage, but a relatively low transfer rate.
2. Dual Band Access Point: The dual band access point supports both 2.4GHz and 5GHz bands, providing higher transmission rates and better performance. The 5GHz band has more interference free channels than the 2.4GHz band, which can provide faster speeds and more stable connections. Dual-frequency access points are suitable for medium sized offices, malls or hotels.
3. Lightweight Access Point: A lightweight access point is a wireless network device that needs to be used with a network controller. Lightweight access points do not have independent management functions themselves, but are centrally managed and configured via a network controller. This type of access point is suitable for large enterprises or organizations to enable centralized management and monitoring of the entire network.
4. Standalone Access Point: A standalone access point is a standalone device that has its own management and configuration functions and does not require additional network controllers. This type of access point is suitable for small businesses or individual users and can provide a simple and easy-to-use wireless networking solution.
5. Scalable Access Point: A scalable access point is a device that can scale on demand, increasing or decreasing the number of access points based on network demand. This type of access point is suitable for places that require flexible scaling, such as large office buildings, schools, or hospitals.
In addition to the types listed above, there are some special purpose indoor access points, such as:
1. Wall-mounted Access Point: A wall-mounted access point can be plugged directly into a Wall power outlet without the need for an additional power cord. This type of access point is suitable for home networks or small offices and can provide easy installation and use.
2. Integrated Antenna Access Point: The antenna of the antenna access point is integrated into the device, and no additional antenna installation is required. This type of access point is suitable for sites that require simple installation and a nice look.
3. Multiple Antenna Access Point: Multiple antenna access points can achieve better signal coverage and performance through multiple antennas. This type of access point is suitable for large venues or high-density user environments, such as conference rooms, stadiums or airports.
To sum up, there are many different types and specifications of indoor access points, which can be selected according to different scenarios and needs. Whether it's a small office, home network or a large enterprise, you can achieve convenient wireless network coverage and connectivity through indoor access points.
