32 PRODUCTS Single-chip baseband processor family second-generation device designed for cost-effective femtocell applications The PC3xx family from picoChip represents a new range of system-onchip baseband processors speciﬁcally targeted at the fast-growing femtocell market. These second-generation devices incorporate the company’s ﬁeld-proven modem software in a highly integrated form, enabling femtocell manufacturers to substantially reduce bill-ofmaterials while increasing performance. The PC302, the ﬁrst member of the family, is a single-chip solution for HSPA femtocells compliant to TR25.820 and the newly standardized Iu-h interface. Supporting up to four users for residential and SME femtocell access points and with data rates of 14.4/5.7-Mb/s in downlink and uplink respectively the PC302 claims to enable the lowest and delivers spare processing power for customer speciﬁc enhancements and additional home networking functions. Layer 1 functionality is provided for release 6 WCDMA, while RNC stacks optimized for the PC302 support standard network architectures including the Iu-h interface to femtocell gateways or SIP/IMS. In addition to 3GPP TR25.820, the chip includes functionality for 2G and 3G network monitoring functions for cell planning and handoff (sometimes described as “cognitive radio” or Self Organizing Networks (SON)) functions and Dynamic Spectrum Management. Enhanced security features are supported for authentication, location detection, encryption and the prevention of DoS attacks. www.mwee.com/208800682 bill-of-materials and lowest power for a femtocell available today. The PC3xx family also offers an upgrade path to more users (picocells), higher performance (Release 7 with HSPA+ and MIMO) and other air-interfaces such as LTE. Fabricated in 65 nm technology, the PC302 device is a complete femtocell solution, supporting up to 14.4 Mb/s HSDPA together with 5.7 Mb/ s HSUPA for 4 connected terminals. It integrates a 3GPP NodeB modem, RNC stack, Radio Resource Management, cryptographic engine, high-speed accelerators, synchronization, network listen functionality and peripherals. The picoArray-based multi-core architecture also enables the ﬂexibility for in-ﬁeld upgrade SP2T electromechanical switch covers DC to 26.5 GHz Narda, an L-3 Communications company, has introduced the Model SEM124 single-pole, doublethrow electromechanical switch that operates from DC to 26.5 GHz with low insertion loss, high isolation, and low VSWR. The switch features a fail-safe mechanism and an integrated indicator circuit. Actuating current is 160 mA at 28 VDC. The insertion loss of the switch ranges from 0.2 dB at 3 GHz to 0.7 dB at 26.5 GHz, and VSWR is 1.2:1 to 3 GHz and less than 1.7:1 at 26.5 GHz. Isolation is at least 50 dB at 26.5 GHz and 80 dB to 3 GHz. Model SEM124 is a member of Narda’s SEM Series of electromechanical microwave single-pole, High-speed software radio PMC module offers 32 programmable DDC channels Pentek has introduced its Model 7152, a quad 200 MHz, 16-bit A/D digitizer with a 32channel digital down converter (DDC). Configured in a PMC format, it employs a highperformance, factory-installed core for users who want to purchase a product with the critical signal processing functions already installed and functioning. It is well suited to fulfill the requirements of real-time software radio, beamforming, signal intelligence and radar systems. The latest addition to the company’s FPGA installedcore, software radio family of products, the 7152 boasts features such as DDC gain and phase adjustments, signal summation and power meters with threshold detectors. The range of decimation has been extended, now programmable from 16 to 8192. The module features 32 power meters that continuously measure the individual average power output of each of the 32 DDC channels. Further, the factory installed IP cores save the user the task of FPGA programming. Another important feature of the 7152, retained from previous designs, is the frontpanel synchronization bus that simplifies integration of larger, multi-channel systems. Software support includes ReadyFlow® Board Support Packages running under Linux, Windows and VxWorks. These are complete software packages that include examples and driver interfaces for the operating system. www.mwee.com/208800683 double-throw switches that are available from stock. They include pulse latching and fail-safe models as well as models with TTL logic control and indicator circuits. In addition to the 26.5 GHz SEM124, there are models that cover DC to 12.4 GHz and DC to 18 GHz. www.mwee.com/208800686 Microwave Engineering Europe ● July/August 2008 ● www.mwee.com http://www.mwee.com/208800682 http://www.mwee.com/208800686 http://www.mwee.com/208800683 http://www.mwee.com
