AS190-73 datasheet

Description :

The AS190-73 is a PHEMT GaAs FET IC high linearity SPDT switch in a SOT-6 plastic package.This switch has been designed for use where extremely high linearity, low control voltage, low insertion loss and ultra miniature package size are required. It can be controlled with positive, negative or a combination of both voltages. Some standard implementations include antenna changeover, T/R and diversity switching over 3 W.The AS190-73 switch can be used in many analog and digital wireless communication systems including cellular, GSM and DECT applications.


1. +2.5 to +5 V Linear Operation P-0.1 dB ≥ 37 dbm
2. Harmonics H2, H3 > 65 dBc @ PIN = 34.5 dBm
3. Low Insertion Loss (0.5 dB @ 0.9 GHz)
4. PHEMT Process

ICE10S01 Datasheet PDF – Controller for Switch – Infineon

Part Number : ICE10S01, Correct Part Number : ICE1QS01

Function : Controller for Quasiresonant Switch

Package : DIP, SOP 8 Pin Type

ICE10S01 pinout

Description :

The ICE10S01 is optimized to control free running flyback converters with and without Power Factor Correction (with PFC Charge Pump).

The switching frequency is reduced in small steps with decreasing load towards a minimum of 20 kHz in standby mode. This function is performed by a digital circuit to avoid any jitter also with periodically pulsed loads. To provide extremely low power consumption at light loads, this device can be switched into Standby Burst Mode. This is also possible without standby control signal (for adapter application).
