LMA406 LOW NOISE PHEMT MMIC • FEATURES ♦ ♦ ♦ ♦ ♦ • 18 GHz to 40 GHz Frequency Band 4.5 dB Noise Figure 12dB Gain 14 dBm Output Power at Saturation +3 V Single Bias Supply DESCRIPTION AND APPLICATIONS The Filtronic Solid State LMA406 is a low noise PHEMT amplifier that operates from 18 to 40GHz. This 2-stage amplifier provides 12dB nominal gain with 4.5dB typical noise figure and 1-dB gain compression power output of +10dBm that is designed for commercial mmW (millimeter-wave) PCN/PCS applications. Ground is provided to the circuitry through vias to the backside metallization. • ELECTRICAL SPECIFICATIONS @ TAmbient = 25°C (VDD = +3.0V, ZIN = ZOUT = 50Ω) Parameter Symbol Frequency Band F Small Signal Gain S21 Test Conditions Min Typ 18 Max Units 40 GHz 30% IDSS (Pad B&D Ground) 9 11.5 dB 30% IDSS (Pad A&C Ground) 9 12.5 dB RS = 0/0Ω 40 80 120 mA ±1 ±2.5 dB 4.5 6.0 dB Saturated Drain Current IDSS Small Signal Gain Flatness ∆S21 Noise Figure NF Input Return Loss S11 -12 dB Output Return Loss S22 -14 dB Reverse Isolation S12 -38 dB Phone: (408) 988-1845 Fax: (408) 970-9950 50% IDSS -32 http:// www.filss.com Revised: 12/5/00 Email: [email protected] LMA406 LOW NOISE PHEMT MMIC • ABSOLUTE MAXIMUM RATINGS Parameter Symbol Test Conditions Drain Voltage VD Operating Current Min Max Units TAmbient = 22 ± 3 °C 4 V IOP TAmbient = 22 ± 3 °C 120 mA RF Input Power PIN TAmbient = 22 ± 3 °C 10 dBm Total Power Dissipation PTOT TAmbient = 22 ± 3 °C .48 W Channel Operating Temperature TCH TAmbient = 22 ± 3 °C 150 ºC Storage Temperature Maximum Assembly Temperature (1 min. max.)
