I need compact TX PA 1W 2.8-3.3 volt 160 MHz + 1/4 λ antenna matching

Hi

I am looking for a good compact PCB solution for VHF (156.525 - 162.025 MHz) TX Power Amplifier that can give 1W (voltage 2.8-3.3 volt)

I also want to use one wire as 1/4 λ antenna and need to match it to my output.

I can choose the output power from those IC´s:

is4060 +13 dBm (20mW)
or
is4063 +20dBm (100mW) [1.8volt gives +14.2dBm (26mW) and 3.3volt gives +23dBm(200mW)]

I also need to be able to switch of the output into sleeping mode (= no current or few uA)

Hope you can help

I have made some calculation for 1/4 λ antenna with small matching coil which will be used as a small spring.

I need to have coil L1 around 7-9 turns, antenna length around 200mm and wire thickness around 0.6. I made the calculation using center frequency 159.275 Mhz
