Matt Purvis from ADI recently took us through a demo of a super-wideband RF transceiver chip that targets the expanding 5G telecom area. The point of the chip is to transmit multi-carrier LTE signals and to simplify the task of designing MIMO systems. Called the ADRV9009, it is a single-chip time division duplex (TDD) design […]
Inside look at a super-narrow band-pass filter-on-a-chip
The days of constructing bandpass filters from discrete components are pretty much over when it comes to the frequencies involved in modern wireless gear. That’s what makes the video we recently did with Alex Rabinovich from AVX interesting. Alex showed us a bandpass filter characteristic that’s super narrow, and the filter that creates also comes […]
Spring pin socket for DC/DC converters handles 25 A
A new socket addresses high current requirements for dual dc-dc converters. The SBT-DC/DC-9002 uses a contactor that is a spring pin with 136-gm actuation force per pin and cycle life of 250,000 insertions. The current capacity of each contactor is 25 A at 20°C temperature rise. Socket temperature range is -55 to +150°C. The socket […]
BGS 121 package socket has 52 GHz bandwidth
A new high-performance elastomer socket is designed for 0.65-mm-pitch BGA packages. The SG25-BGA-2051 socket is designed for a 8×8-mm package size and operates at bandwidths up to 52 GHz with less than 1 dB of insertion loss (GSSG configuration). The contact resistance is typically 20 mΩ/pin. Network analyzer reflection measurements for the G-S-S-G case were […]
Clamshell production test socket for BGA1062
A new Stamped spring pin socket addresses high-performance requirements for testing BGA1062 packages. Called the CBT-BGA-6077, it has a contactor that is a stamped spring pin with 31-gm actuation force per ball and a cycle life of 125,000 insertions. The self-inductance of the contactor is 0.88 nH, insertion loss < 1 dB at 15.7 GHz, […]
Production test socket handles 216-lead quad flat pack devices
A new Stamped spring pin socket addresses high-performance requirements for testing 216 lead Quad flat pack – CBT-QFE-3014. The contactor used in CBT-QFE-3014 socket is a stamped-spring pin with 17-gram actuation force per ball and cycle life of 10,000+ insertions. The self-inductance of the contactor is 0.88 nH, insertion loss < 1 dB at 31.7 […]
Open-top socket for BGA240 provides 27-GHz bandwidth
A new high-performance BGA socket for 1-mm pitch, 240-pin BGA ICs called the SG-BGA-6475 socket is designed for IC size – 17×18-mm package size and operates at bandwidths up to 27 GHz with less than 1 dB of insertion loss. The contact resistance is typically 20 mΩ per pin. The socket connects all pins with […]
On-chip RF transformers could shrink thanks to rolled-up membrane design
Researchers at the University of Illinois say they have devised more efficient RF transformers by depositing conductors on a membrane that, once complete, rolls up to create a high-turns-ratio transformer. The transformers consist of two sets of rolled-up coils deposited on some kind of SiNx material. Researchers say they’ve used the technique to realize up […]
Elastomer sockets for high-speed QFP ICs handle up to 30 GHz with below 1 dB insertion loss
A new high-performance QFP socket for 0.5-mm-pitch 64-pin QFPs called the SG-QFE-7020 socket is designed for 10x10x1.6-mm packages with 12×12-mm lead tip-to-tip. It operates at bandwidths up to 30 GHz with less than 1 dB of insertion loss. The contact resistance is typically 20 m° per I/O. The socket connects all pins with 30-GHz bandwidth […]
Bulk acoustic wave filters make life easier for Wi-Fi front-end designers
BAW filters help overcome the biggest challenges facing Wi-Fi front-end designs, including thermal management, interference, and RF linearity. Cees Links |Qorvo Wireless Connectivity Smart homes are getting smarter. So they increasingly make heavy demands on their internet routers, so much so that traffic demands are exceeding the capacity of the single-router model. Retailers and businesses […]
