I have simulated Qorvo TQL9044 LNA (internally matched for 1.5GHz to 4GHz band).
At 5.2GHz (out Band), simulation responses are :
S11 (IRL) is -0.47dB; S22(ORL) is -5.8dB and S21(gain) is -4.96dB.
Question: If I feed -20dBm as input power to this LNA at 5.2GHz then what will be the...
There are 6 different channels or filters ( based on frequency ) to route the RF signal. Each channel or filter is made up of a circuit containing a set of PIN diodes.
To switch on to the particular channel or filter (let say channel-1)PIN diodes of that...
Check the attached jpeg file (schematic n description) regarding circuit of IRF6216pbf MOSFET.
IRF6216pbf is a HEXFET mosfet from International Rectifiers.
I am using it to switch on/off the PIN diode based RF channel.
TO switch OFF the channel, PIN diode should be biased with -75V and to...
I need to have Bias Sequence card for GaN based Power Amplifier.
GaN based device needs sequencing , Gate voltage (-5V to -2V) first and then Drain voltage (Vd) (28 to 50V).
I have followed the app note (attached here) for my requirement. I have placed N-Channel MOSFET (PSMN8R2-80YS) in...
I am designing a power supply for a RF switch filter bank (SFB).
This SFB has six channels and only one channel will be activated at one time. It means one channel on & other five channels will be off for
an instant of time.
Conditions for switching ON the channel (consists of series n...
I want to design a Power Amplifier system having Basic requirements :
1. Frequency BW : 1GHz (UHF range)
2. RF output : 10W (linear)
3. Return Losses: -10dBm or less
Here challenge is to have constant gain over the 1GHz of Bandwidth.
I am browsing the vendor's websites n...
I am working on RFID project.
I am using TI TRF7960 IC which is to be controlled by PIC18F4420.
During coding I am getting problem.
Kindly check the attachment and suggest me.
Thanks & regards,
