RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

RF Micro Devices® Press Release - November 29, 2011
RFMD Intros RFSA4013 and RFSA4023
Sr. Manager, Communications
|FOR IMMEDIATE RELEASE NOVEMBER 29, 2011
RFMD's new RFSA4013 and RFSA4023 are
fully monolithic analog Temperature-Compensating
Attenuators (TCAs) featuring exceptional linearity
over their entire gain control range. These
TCAs are designed to offset the gain reduction
of an RF component over temperature without
the need for closed loop feedback. Three customer
selectable temperature coefficients make these
TCAs a flexible solution for RF lineups. Each
attenuator incorporates revolutionary new circuit
architecture that solves a longstanding industry
problem with regards to attenuator architecture:
high IP3, low DC current, and broad bandwidth.
Traditional approaches for linear temperature-compensating
devices require expensive co-fired ceramics
with temperature-sensitive materials or current-hungry
PIN diodes with elaborate area consuming control
circuits. The RFSA4013 and RFSA4023 only require
a single supply voltage and two logic bits to
set the control attenuation slope versus temperature.
Each TCA draws a very low 1mA current and is
packaged in a small 3mmx3mm QFN. These attenuators
are internally matched to 50Ω over their rated
control range and frequency.
