TWT TH 3976/3977 PEAK ------- TH 3976/3977行波管
SATCOM UPLINKS系列
Ku-band high power TWT series for SATCOM Uplinks: up to 750W
Ku波段的高功率SATCOM Uplinks行波管系列:高至750W
Drawing on Thales experience of over 60 years in developing Periodic Permanent Magnet focused Traveling Wave Tubes
(TWTs) for space-based and ground-based satellite telecom applications, the TH 3976 –TH 3977 series features a two-stage
collector design for a high efficiency (>42%).
THALES有着近60年的基于航空或者地面卫星通讯使用的行波管的开发经验,TH 3976 – TH 3977系列行波管是高功
效(>42%)的两级收集器。
The TH 3976 – TH 3977 TWT peak mode series operating in the full Ku-band, offers a typical gain of 45dB minimum from
13.75 to 14.5 GHz and delivers an exceptional output power up to 750W peak with an intermediate version of 400W. The
TH3976 – TH 3977 TWT series has been developed for high linearity, optimized dissipation and size.
TH 3976 – TH 3977行波管峰值模式系列是全Ku波段的,可以在13.5到14.5GHz范围内提供最低45dB标准增益并且
能够产生高至750W的输出功率峰值并400W的中间功率版本。TH 3976 – TH 3977行波管系列已经可以开发到高线
性度,最优化损耗以及最佳尺寸。
The TH 3976 – TH 3977 TWT series is RoHS compliant through exemption (directive 2002/95/EC). Thales TWTs are
designed, developed and manufactured at a production plant certified to ISO 900: 2000 and ISO 14001.
TH 3976 – TH 3977行波管系列是无铅产品(2002/95/EC)。THALES行波管的设计、开发以及生产车间已经获取了ISO900:

SATCOM Uplinks
Thales TH 3976 – TH 3977 traveling Wave Tubes series has been chosen by most civil and military satellite operators
around the world to support growing demand for new high bandwidth Ku-band Satcom uplinks largely deployed
everywhere.
THALES TH 3976 – TH 3977行波管系列已经成为全世界大多数民用以及军用卫星使用者的选择,并新一代的宽Ku波
段Satcom Uplinks系列产品的需求数量也在进一步在各处不断的扩大。
Our TH 3976 – TH 3977 TWT peak mode series is widely used for large earth station uplinks and mobile antennas: Satcom
on the halt and Satcom on the move. Thales has delivered thousands of Ku-band units to date, and we are still investing in
new production capacity to ensure quick delivery for the TH 3976 – TH 3977 TWT series with a capacity of a few hundred
per year.
我们的TH 3976 – TH 3977峰值模式系列已经在地面站以及移动天线方面得到了充分的应用:固定使用SATCOM,移
动也使用SATCOM。THALES目前已经有数以千计的ku波段订单,并且我们还在以每年几百只的数量不断投资扩大
生产线以保证TH 3976 – TH 3977行波管的快速生产周期。
Thales is at the cutting edge of Ku-band technology, with an important heritage coming from the Space TWTs activity at
Thales, providing to our customers a very high level of reliability.
THALES承袭了航空行波管的科学技术,如今又站在了Ku波段科技的前沿,为我们的客户提供更高可靠性产品。
