Family of RF ICs Customized for Bluetooth

Fri, 04/06/2001 - 5:21am
Toshiba America Electronic Components (TAEC) announced that it has expanded its family of RF integrated circuit (IC) packages called Cell Packs. These new Cell Packs offer designers a quick and easy way to implement a variety of important functions required for mobile communications products and Bluetooth™-enabled devices.

Each RF Cell Pack eliminates the need for multiple discrete devices required to perform specific functions such as wide band amplifier, mixer, attenuator, and single-pole double-throw (SPDT) switch. The extended family now includes three-wideband amplifier Cell Packs for low voltage operation, Cell Packs for crystal oscillator functions, and Cell Packs for SPDT switch functions. As a result, RF designers can reduce total system component count, save board space and shorten the design cycle.

Toshiba Corp.'s wideband amplifier Cell Packs, designated TA4011FU/AFE, TA4012FU/AFE and TA4016AFE, are housed in ultra-compact surface mount device (SMD) packaging, and are ideal for PDA, cellular phone, portable computer, set-top box and tablet PC applications.

For crystal oscillator functions, required by all portable communications devices, Toshiba's TA4014FT/FE and TA4015FT/FE reduce start time and noise while providing excellent stability at a low operating voltage range. These devices are packaged in a 6-pin TU6 or ES6 package.

Toshiba's TG2210FT microwave monolithic IC (MMIC) Cell Pack is targeted at SPDT switch functions, for Bluetooth devices. The TG2210FT is manufactured using a high-performance gallium arsenide (GaAs) process making it ideal for the 2.4 GHz Bluetooth band. Housed in an ultra-compact TU6 package, it features high isolation of 30 dB (typ.) with very low insertion loss of 0.4 dB (typ.) at V c1 = 2.5 V, V c2 =0V, Pi=0 dBm W.

Toshiba also offers RF varactor diodes for voltage control oscillator (VCO) tuning applications. In addition, Toshiba's RF power transistors meet the low-voltage and high linearity requirements of Bluetooth-enabled portable communications devices including cellular phones, PDAs and portable computers.
