BAR 90-081LS - world's smallest 4-in-1 PIN diode array for multiple-band antenna switching

Infineon BAR90-081LS

‘Thin, small, and light’ is a basic trend for all future mobile and portable devices such as cellular phones, personal multimedia players and PDAs.

In such devices, either a PIN diode-based discrete solution or an integrated switch IC is usually used for band switching or antenna switching. RF Frontend design engineers continuously look for cost-attractive and size-compact solutions to reach the best price performance combination.

As the world’s smallest 4-in-1 PIN diode array housed in an innovative 8-pin leadless TSSLP8 package – the Infineon's BAR 90-081LS perfectly combines the cost advantage of discretes-based solution with a much higher integration level than single diodes.

The BAR 90-081LS also offers the possibility to customize each diode’s direction (either horizontal or vertical) according to the customer’s design preference. It enables a low-cost and mini-dimension double-input/double-output switching solution for multiple-antenna systems or dual-band/triple-band cellular phones.

Features

  • Extremely small form factor: L×W×H = 1.34 × 0.74 × 0.31 mm3
  • Flexible internal diode positioning and configurations
  • Low forward resistance
  • Low capacitance at zero volt reverse bias for high working frequency range
  • Well-balanced harmonic distortion in ON / OFF status

Applications

  • Antenna switch module for dual-band or triple-band cellular phones
  • Multiple-antenna RF systems – for example, MIMO WLAN routers, MIMO WiMax receivers, etc.
