Bluetooth Switch MMIC Developed The industry's highest performance and smallest package in a 2.4 GHz ISM band device.
SPM3204
Overview
Bluetooth is now seen as a standard for wireless communication with rapid growth potential in the world market. Applications for spread-spectrum communication using the 2.4 GHz ISM band (industrial, scientific, and medical frequency band) that includes Bluetooth*1 have now grown to include a wide variety areas. These include the 2.4 GHz cordless telephones introduced to the US market last year, the wireless LANs that now achieve 11 Mbps under the IEEE 802.11b standard and thus provide a significantly larger capacity than the earlier 2 Mbps LANs, wireless audio, and home RF*2. Sanyo has now developed the SPM3204 MMIC (Monolithic Microwave IC) that, as a communication switch for the 2.4 GHz ISM band that includes Bluetooth, achieves the industry's smallest size, highest performance, and lowest number of external components. The SPM3204 achieves the industry's highest performance in four areas of importance to 2.4 GHz ISM band communication. (1) The SPM3204 achieves the industry's lowest insertion loss of 0.65 dB in a 2.4 GHz ISM band device. Insertion loss is the loss that occurs when the high-frequency power passes through the device. (2) It achieves linearity characteristics of 30 dBm for a PIN of 1 dB. This characteristic expresses the distortion level in the output for a high-frequency input signal. (3) It achieves a VSWR*3 of 1.1. This expresses the reflections internal to the switch of the high-frequency input signal. (4) It also assures an isolation of 18 dB in the 2.4 GHz ISM band. This characteristics expresses the amount of leakage in the off side of the switch. Achieving these results required developing a variety of new technologies, and Sanyo has applied for patents in these areas. Sanyo has a solid track record as a supplier of high-performance GaAs switching ICs in the industry's smallest packages with the smallest number of external components to the mobile equipment market such as cellular telephones, mainly for the 1 to 2 GHz band. While this new device inherits those features directly, it was designed especially for applications with frequencies over 2 GHz, and features drastic design optimizations in all of the circuit, device, process, and layout aspects. These optimizations have allowed Sanyo to establish optimal GaAs switch IC technologies for the 2.4 GHz ISM band, which is expected to show rapid growth in the near future. *1. Bluetooth: A communication specification that improves the mobile and business work environments by providing mutual wireless interconnection between cellular telephones, notebook personal computers, PDAs, digital cameras, and other peripheral equipment.

PRODUCT INFORMATION
*2. Home RF: A communication specification that provides mutual wireless interconnection in the home between personal computers, cordless telephones, AV equipment, and other digital devices. *3. VSWR: Voltage standing wave ratio. The ratio between the maximum and minimum levels of voltage standing waves that occur between incident wave and reflected waves that occur at discontinuities in the high-frequency transmission path. A VSWR of 1 is ideal and corresponds to zero reflection in the system.
Features
* Achieves the industry's lowest class insertion loss of 0.65 dB in the 2.4 GHz ISM band. * Achieves linearity characteristics of 30 dBm for a PIN of 1 dB. * Achieves a VSWR of 1.1. * Guarantees an isolation of 18 dB in the 2.4 GHz ISM band. * Control voltage: Uses a 0/+3 V single-voltage power supply. * Achieves the industry's smallest number of external components: 3 components. * Highly resistant to damage from ESD. * Provided in the 2.0 x 2.1 x 0.9 mm3 MCP6 package, which is the industry's smallest package used for an RF IC switch.
