Please note: SKY12348-350LF is being discontinued and is not recommended for new designs.
The SKY12348-350LF is a GaAs pHEMT four-bit broadband digital
attenuator with a 1 dB Least Significant Bit (LSB). The attenuator
features low insertion loss, excellent attenuation accuracy, a
15 dB attenuation range, and high linearity performance. The
SKY12348-350LF is an ideal choice for a wide variety of cellular
3G and 4G infrastructure applications.
Attenuation is controlled by four DC control pins (V1, V2, V3, and
V4). Depending on the control bias, the attenuation state between
the RF1 and RF2 pins can vary between a low insertion loss state
or up to 15 dB.
The device is provided in a 3 x 3 mm, 16-pin Quad Flat No-Lead
(QFN) package.
