Pasternack Enterprises, Inc., a leading manufacturer and supplier of RF, microwave and millimeter wave products, announces the release of their new 5, 8 and 10 bit broadband PIN diode digital step attenuators with performance up to 40 GHz depending on the configuration.
Pasternack Enterprises, Inc., an industry-leading manufacturer and supplier of RF, microwave and millimeter wave products, debuts an entirely new family of high isolation PIN diode switches consisting of three low insertion loss, high isolation and high speed modules, covering a frequency range of 1 to 12 GHz.
RFMW Ltd. announces design and sales support for Skyworks SKY16601-555LF PIN diode limiter module covering the frequency range of 0.5 to 6.0 GHz. The SKY16601-555LF addresses a growing need for receiver low noise amplifier (LNA) protection in microwave applications.
Linear Technology Corp. announces the automotive (H-grade) and high reliability military (MP-grade) versions of the LT4320, an ideal diode bridge controller for 9 to 72 V systems. The LT4320 replaces a full-wave diode bridge rectifier with a low loss N-channel MOSFET bridge to reduce the power and voltage losses by a factor of ten or more. Power supply size is reduced as the enhanced power efficiency eliminates bulky heat sinks.
Linear Technology Corp. announces the LT8309, a flyback secondary-side synchronous rectifier driver that replaces the output diode with a MOSFET, allowing up to 10A output current without the use of a heat sink. The maximum output current of a flyback power supply has been limited by the power loss and heat generated from the output diode when no heat sink is used.
The LT3905 from Linear Technology is a fixed frequency, current-mode step-up DC/DC converter designed to bias avalanche photodiodes (APD) in optical receivers. The LT3905 features high side APD current monitoring with over five decades of dynamic range and better than 2% relative accuracy over the 3µA to 3mA range. The maximum APD current is programmed with a single resistor and a fast current limiter with indicator protects the APD during overload conditions.
Linear Technology Corp. introduces the LT4321, an ideal diode bridge controller that replaces two diode bridge rectifiers with low-loss N-channel MOSFET bridges to increase the available power and reduce heat dissipation in a Power over Ethernet Powered Device (PoE PD). IEEE 802.3 PoE specifications require PDs to accept DC supply voltages of any polarity over their Ethernet inputs.
