CHT4012-98F
RoHS COMPLIANT
DC-6GHz 6-BIT DIGITAL ATTENUATOR
GaAs Monolithic Microwave IC
Description
The CHT4012-98F is a DC-6GHz monolithic
6 bit digital attenuator with a LSB = 0.5dB
offering a high dynamic range and a high
accuracy, the RMS amplitude error is
typically as low as 0.3dB. The circuit provides
low insertion loss 2.5dB associated to input
and output return losses better than 14dB. A
CMOS and TTL compatible interface is
available on chip.
The circuit is mainly dedicated to defence
and space systems and is also well suited for
a wide range of microwave applications and
systems.
The circuit is manufactured with a pHEMT
process, 0.25µm gate length and electron
beam gate lithography.
It is available in chip form

DC-6GHz 6-BIT DIGITAL ATTENUATOR CHT4012-98F
Definitions
n: Attenuator state index with 0 n 63
Phase_S21(n):
Measured phase of S21 in degree at attenuation state n
dB_S21(n):
Measured magnitude of S21 in dB at attenuation stateni
Attenuation Error (Att_err)
Att_err(n)= dB_S21 (n) - dB_S21(0) 0.5xn (dB)
Att _ err (n)
The translation of Att_err(i) from dB to linear is given by: Att_err_lin(n) = 10 20
Phase variation (Phivar)
Phivar(n) = Phase_S21(n) - Phase_S21(0) (°)
