UMTS Band 4 Duplexer with RX Port The Avago ACMD-4104 is a highly miniaturized duplexer designed for use in the UMTS Band 4 (1710-1755 MHz UL, 2110-2155 MHz DL) handsets and mobile data terminals. Low insertion loss in the Tx channel minimizes current drain from the power amplifier, while low Rx channel insertion loss improves receiver sensitivity. The Rx port is balanced (100 ohms) to preserve Common-Mode Rejection Ration (CMRR) and simplify the interface to baseband chipsets...Read More
4A Synchronous Buck Converter The TPS56428 is an adaptive on-time D-CAP2™ mode synchronous buck converter. The TPS56428 enables system designers to complete the suite of various end-equipment power bus regulators with a cost effective, low component count, low standby current solution. The main control loop for the TPS56428 uses the D-CAP2™ mode control that provides a fast transient response with no external compensation components. Advanced Eco-mode™ allows the TPS56428 to maintain high efficiency during lighter load conditions...Read More
High ESD-Protected Transceiver The MAX14770E is a half-duplex, ±35kV high ESD-protected transceiver for PROFIBUSDP and RS-485 applications. In addition, it can be used for RS-422/V.11 communications. The MAX14770E is designed to meet IEC 61158-2, TIA/EIA-422-B, TIA/EIA-485-A, V.11, and X.27 standards. The MAX14770E operates from a +5V supply and has true fail-safe circuitry that guarantees a logic-high receiver output when the receiver inputs are open or shorted...Read More
