GaAs MMIC DBS 4
×
2 IF Switch
DESCRIPTION
The
µ
PG183GR is intended for use in Direct Broadcast Satellite (DBS) applications within the Low Noise Block
(LNB) down-converter for systems where at least two LNB outputs are required.
It offers 4 intermediate frequency amplifier channels that can independently select 1 of 4 IF inputs. It is loused in
a very small 16-pin plastic HTSSOP package available on tape-and-reel and easy to install and contributes to
miniaturizing the systems.
FEATURES
• 4 independent IF channels
• Integral switching to channel input to either channel output
• Frequency range
• Insertion loss per channel
• Channel to channel isolation
: 950 to 2 150 MHz
: 7.0 dB TYP. (Z
O
= 50
Ω)
: 26.5 dB TYP.
• Small 16-pin HTSSOP Package
