Card power chip meets smart and SIM standards
The LTC4557 is a dual SIM/smart-card power supply and level translator, which provides both 1.8 and 3V SIM power and digital signal level shifting from a 3 x 3mm QFN package.
RF mixers take transformers onboard
Linear Technology has released two new high linearity up-converting RF active mixers with integrated RF transformers.
Using a single 3V supply, the LTC6406's differential outputs each swing from near ground to 2V.
As a result, this amplifier is ideal for level shifting signals to match the input range of 12 to 16bit single-supply differential-input ADCs.
The LTC6406 is built for speed, performance and power efficiency.
Its gain-bandwidth product is 3GHz, and its unity gain -3dB bandwidth is 800MHz.
The LTC6406 achieves -90dBc distortion performance for input frequencies from DC to 20MHz, and nearby -70dBc distortion performance from DC to 50MHz.
Noise is just 1.6nV/(rt)Hz.
Running from 2.7 to 3.5V supplies, the LTC6406 is fully specified at 3V, and so it can share the power supply used by many ADCs.
Current consumption is just 18mA, which can be reduced to 300uA during periods of inactivity by use of a shutdown feature.
"The LTC6406 achieves excellent dynamic performance with low power consumption", says Kris Lokere, Design Manager at Linear Technology.
"Its patent-pending rail-to-rail input stage simplifies the task of translating a ground-referenced or supply-referenced signal to the input range of popular high speed ADCs such as the LTC2206.
The LTC6406 is available in a 3 x 3mm 16-lead QFN package in both commercial (0 to 70C) and industrial (-40 to +85C) temperature ranges.
