Constant Impedance K|Z| SP2T RF Switch
GENERAL DESCRIPTION
The F2923 is a low insertion loss 50Ω SP2T absorptive
RF Switch designed for a multitude of wireless and
other RF applications. This device covers a broad
frequency range from 300 kHz to 8000 MHz. In
addition to providing low insertion loss, industry
leading isolation at 2 GHz and excellent linearity, the
F2923 also includes a patent pending constant
impedance (KZ) feature. KZ minimizes LO pulling in
VCOs and reduces phase and amplitude variations in
distribution networks. It is also ideal for dynamic
switching/selection between two or more amplifiers
while avoiding damage to upstream/downstream
sensitive devices such as PAs and ADCs.
The F2923 uses a single positive supply voltage of
3.3 V supporting three states using either 3.3 V or
1.8 V control logic. An added feature includes a
ModeCTL pin allowing the user to control the device
with either 1-pin or 2-pin control.
COMPETITIVE ADVANTAGE
The F2923 provides constant impedance on all ports
during transitions without compromising isolation,
linearity, or insertion loss.
