Family of RF ICs Customized for Bluetooth
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.
