Philips Semiconductors Objective specification
UHF amplifier modules BGY120A; BGY120B
FEATURES
• Single 3.5 V nominal supply voltage
• 1 W output power
• Easy control of output power by DC voltage
• Very high efficiency (typ. 60%)
• Silicon bipolar technology
• Standby current less than 10 µA.
APPLICATIONS
• Hand-held transmitting equipment operating in the
824 to 849 MHz and 872 to 905 MHz frequency ranges.
DESCRIPTION
The BGY120A and BGY120B are two-stage UHF amplifier
modules in a SOT482B package with plastic cover. Each
module consists of two NPN silicon planar transistor dies
mounted together with a matching and bias circuit
components on a metallized ceramic substrate.
These modules produce an output power of 1 W into a
load of 50 Ω with an RF drive power of 5 mW.
