Tyco Electronics announced the availability of the M/A-COM MASW-000822-12770T, a new SP2T broadband PIN diode switch for 0.5 to 6 GHz applications.
The switch is ideal for higher power WiMAX (Worldwide Interoperability for Microwave Access) base station and military radio applications and features high linearity and power handling. The device provides over 8 W (C.W.) power handling coupled with 65 dBm IIP3 for maximum performance.
The M/A-COM MASW-000822-12770T is a SP2T, high linearity, common anode, asymmetrical PIN diode switch in a 3 mm PQFN package. It is ideal for use in 2.3 to 2.7 and 3.3 to 3.8 GHz WiMAX base station applications, where LNA protection is required. In the transmit antenna state at 3.8 GHz, the switch provides a remarkable 0.35 dB loss and 27 dB transmit-receive isolation to protect the LNA.
The switch is capable of handling 39 dBm C.W. and 43 dBm peak power, at 3 μS pulse width, with 1 percent duty cycle. The high linearity PIN diode design produces an exceptional 0.8 percent EVM value at 3.5 GHz (transmit state), 8 W incident power with OFDM modulation. Accordingly, at 3.8 GHz, the switch provides 0.5 dB loss and 22 dB transmit-receive isolation in the antenna-receive state for the receive function. The switch can operate from +5 V, +12 V and + 28 V or +5 V and -15 V D.C. power. M/A-COM also provides a line of PIN diode drivers compatible for these switches.
The MASW-000822-12770T is priced at $1.98 in quantities of 10,000 pieces. Contact Tyco Electronics’ M/A-COM products domestic and international sales channels for price and delivery quotes. Data sheets and supporting technical documents are available on-line at www.macom.com.
