PRELIMINARY DATA SHEET
GaAs INTEGRATED CIRCUIT
PG2121TB
L-BAND UP/DOWN CONVERTER
DESCRIPTION
The µPG2121TB is L-band up-converter or down-converter IC (LO Buff. Amp. + Passive Mixer). The device can
convert the RF frequency to IF frequency and operate low current. It housed in an original 6-pin super minimold
package that is smaller than usual 6-pin minimold easy to install and contributes to miniaturizing the system.
FEATURES
• +2.8 V single voltage
• Low distortion (IIP3 = +23 dBm TYP.)
• Low current operation (IDD = 3.5 mA TYP.)
• LO buffer amplifier and passive mixer on a single chip
• 6-pin super minimold package (Size: 2.0 × 1.25 × 0.9 mm)
APPLICATION
• L-band digital cellular etc.
