PRELIMINARY DATA SHEET
L, S Band SPDT GaAs MMIC Switch UPG154TB
DESCRIPTION
FEATURES
The UPG154TB is an L-band SPDT (Single Pole Double
Throw) GaAs FET switch for digital cellular or cordless tele-
phone application. The device can operate from 100 MHz to
2.5 GHz with low insertion loss. This device is housed in an
original 6 pin super mini-mold package similar to SOT363.
• LOW INSERTION LOSS:
LINS = 0.65 dB TYP at VCONT = +3.0 V/0 V, VDD = +3 V,
CX = 2 pF, f = 2 GHz
• HIGH POWER SWITCHING:
Pin (1 dB) = +30 dBm TYP at VCONT = +3.0 V/0 V,
VDD = +3 V, CX = 2 pF, f = 2 GHz
NEC's stringent quality assurance and test procedures assure
the highest reliability and performance.
• SMALL 6 PIN MINI-MOLD PACKAGE:
Size: 2.0 x 1.25 x 0.9 mm
APPLICATION
• L, S-BAND DIGITAL CELLULAR OR CORDLESS
TELEPHONE
• PCS, WLAN AND WLL APPLICATIONS
ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, TA = 25°C, VCONT1 = 3 V, VCONT2 = 0 V or VCONT1 = 0 V, VCONT2 = 3 V; off chip DC blocking capacitor value, 51 pF)

Note:
1. When the UPG154TB is used, it is necessary to use DC blocking capacitors for the RF input and RF output. The value of DC blocking
capacitors should be chosen to accommodate the frequency of operation. The range of recommended DC blocking capacitor value is less
than 100 pF.
2. The distance between IC's GND pin and ground pattern of substrate should be as short as possible to avoid parasitics.
