Description
HPA-820 is a 16Watt output (min.
@P3dB) RF PowerAmplifier; within
frequencies of 760 to 880MHz; operating
from a single 12VDC power supply (915VDC usable, but not recommended).
Electrical Specifications @ +25°C, Zin=Zout=50Ohm, Vsupply = +12VDC
IMPORTANT: MUST USE ACTIVE COOLING IF CASE TEMP. EXCEEDS 65ºC or to ACHIEVE MAX. RFpower Output over 12W upto 20W (over +41dBm upto +43dBm), keeping under 18W recommended.

APPLICATION NOTES (reliability):
• Thermal:
Specifications shown above as graphs, are at room temperature (23-25ºC i.e. in a controlled
environment), per international standard. If Amplifier's temperature is let rise significantly (e.g. towards
max. 65-70ºC) in customer's use, DCpower (supply) current may rise and stabilize at approx. 200-450mA
higher values vs. shown in graphs, especially if at the same time RF PowerOut is driven beyond approx.
9Watt (contributing to selfheating, besides ambient temperature) - which is normal. Such increase in
DCsupply current due to higher than standard ambient temperature, is less pronounced at low RF
PowerOut; at below 1Watt it may add less than 90mA vs. current @25ºC. Amplifier is designed to
operate normal at ANY temperature or RF PowerOut within specs, this notice is only a recommendation
to expect higher DCcurrent if user allows heat build-up far above standard 25ºC.
Stock Heatsink is removable & upgradeable by the user, additionally Mountplate (opposite of heatsink) is
strongly recommended to mount on a surface conducting heat away (e.g. mass of metal); some customers
use active cooling such as fans (for extreme environment, even liquid cooling is an option), however be
careful to not generate ElectroStatic Fields harmful for RF/Microwave devices. Use of inadequate
Heatsink or HeatSpreader instead of stock, or inappropriate thermal-interface-material (TIM, i.e. grease,
paste, semi-solids) voids warranty; RF Bay Inc. reserves the right to determine if a unit submitted for
warranty service had been thermally abused. The key to reliability, is not only to minimize temperature
rise, but also avoid repetitive thermal gradient (shock) due to cold-hot-cold cycling; these Amplifiers are
meant for Commercial (rather than Mission-Critical) Mobile communications; in particular in Base & Fixed
station applications with long-term continuous transmission and a higher On-Off frequency, please
consider derating, redundancy system, maintenance schedule, or otherwise assure reliability.
• Oscillation & Load VSWR:
This amplifier's rugged design can withstand Load VSWR mismatch upto 6:1 (no
degradation/destruction), guaranteed stable (no parasitic self-oscillation) for Pout<20Watt & Load VSWR
under 3:1. If oscillation is observed, check if Load & Source impedances ZL = ZS = 50 Ohm; adding
DCpower decoupling ceramic + electrolytic capacitors (in parallel, closest possible to amplifier & minimal
parasitic inductance to Ground) may help but not necessary, because already present internally.
• ESD:
Sensitive to ESD voltages to approx. 1KiloVolt - as typical for RF/Microwave amplifiers, appropriate ESD
precaution is required.
