Technical content
Features
- Broadband gain with 1.4V-3.3V single-supply
- High gain : (18.7-10.7) dB at (1.5 - 8) GHz
- Low-noise : (1.5 – 2.8) dB at (1.5 -8) GHz
- Low power operation at 18mA nominal current
- Internally matched to 50 Ohm at RF output
- CMOS-compatible variable bias control and shutdown pin
- GaAs E-pHEMT Technology[1]
- Low cost, low-profile package : (2.5 x 2.5 x 0.55) mm3 Typical Performance At 3.5GHz; 1.4V, 17 mA (typ) :
- 17.6 dB Gain
- 1.4 dB Noise Figure
- IP1dB : -12.3 dBm
- IIP3 : -3.3 dBm
- Shutdown current : < 200uA
Applications
- LNA for GPS, WCDMA, IEEE 802.11g/a, 802.16e
- Low-noise 50-Ohm Gain-block
- Broadband LNA for multistandard, multiband radio Note: 1. Enhancement-mode technology employs positive Vgs, thereby elim- inating the need of negative gate voltage associated with conven - tional depletion mode devices.
